In the Glee season finale, Emma revealed to Will that she was over him and dating her dentist now. Spoiler alert, but rumors all around the internet are that former “Uncle Jesse” actor John Stamos has been pegged to join Glee next fall as said dentist.

Stamos should prove a worthy rival to Schuster; even if he plays the role with a hint of villainy and is closer in age to Sue Sylvester than Emma, he still comes off with the charm of a guy who’s spent hours in the gym after downing some particularly effective vitamin supplements.

Could a sing-off between the two suitors be far behind? This is Glee… what do you think?

The first season isn’t even over, the second season hasn’t even gone before cameras, and already Fox has decided it’s so hot on the musical comedy Glee that they have approved it for a third season; Glee’s second-season renewal came late in 2009.

But that’s not all; the producers are also reportedly negotiating with Fox to expand Glee’s future seasons from the standard 22 episodes to 25-episode orders. The reason behind this has more to do with merchandising that storytelling, however.

You see, each of Glee’s soundtracks have become instant iTunes best-sellers and the physical CDs even sell well enough to impact the top of Billboard album sales charts. Glee recently also surpassed a record held by U2 for the most charting singles in history… or something like that.

By expanding a season order of Glee from 22 episodes to 25, producers figure to add an additional soundtrack release to each season of Glee they produce in the future.

This season has seen Glee spawn three volumes of musical soundtracks based on season one, as well as a standalone EP-sized soundtrack for the special “Power of Madonna” episode. A volume four soundtrack is expected over the summer, sometime after the season finale airs.

That’s four full-sized soundtracks, plus one Madonna-power EP soundtrack. By adding three additional episodes, that number could expand from five to as many as six or even seven soundtrack releases per season, counting special EP releases in the vein of the Power of Madonna EP.

The point is, the multimedia approach to Glee is helping both the producers and the network make money hand-over-fist through non-traditional revenue streams, and an early green-light on the third season helps keep costs low before stars and producers start asking for improved contracts. Of course, if the ratings are still strong mid-way through the third season, producers can always avoid expensive re-negotiations with most of the cast by the very nature of the show: Glee’s biggest breakout star, Lea Michele, portrays a high school sophomore in season one, so a season four would be unlikely anyway; so long as new cast members are added every season and current stars are cycled out as they “graduate,” the show can avoid becoming overly expensive to produce by constantly being a launching pad for new talent, rather than a long-term showcase for any one star… even Lea Michele.

Setting Glee in high school among the Acneticin-needing crowd, therefore, was a wise way for producers to structure the show for long-term success.

Of course, the fact that Glee’s ratings significantly improved in the second half of the first season, following American Idol, played no small part in securing that third season renewal early. If all goes well, Fox may even have Simon Cowell’s new musical talent showcase, X-Factor, to pair with Glee in the fall!

Glee star Iqbal Theba, who plays Principal Figgins on Fox’s musical comedy, has revealed a major plot point prior to the April debut of the second half of the show’s first season: The uptight principal will be caught in a compromising position with Jane Lynch’s Sue Sylvester!

How the development plays into the storyline of the rest of the season remains to be seen, but at the end of the first part of the season, Sylvester was vanquished and promised glee-club coach Will that she’d go on a brief vacation, come back tan and rested and “more committed than ever to bring you down, Will Schuster.”

The principal may want to get a solid sexual harassment insurance quote, because it’s a half-decent guess that Sylvester gets Figgins in the compromising position to gain leverage to regain her power position over Will. Still, we’ll have to wait until Glee’s April debut to see just how it all plays out!

Glee, which will have it’s season-one bow on June 8 and is already renewed for a second season, has just nailed down a Horrible guest star. Doctor Horrible, that is; How I Met Your Mother’s Neil Patrick Harris.

Unlike some stars who prefer to spend their spare time hawking auto insurance quotes, Harris found a gap in his HIMYM schedule to fit in a guest spot on the musical comedy, Glee, allowing him a chance to show off his singing ability once again after a dazzling and humorous performance in Joss Whedon’s Dr. Horrible, as well as a musical number extolling the virtues of suits earlier this season on How I Met Your Mother.

Glee returns on April 13 on Fox.

Glee has moved to the head of the class, so to speak; after taking a load of herbal diet supplements, the cast was overjoyed to hear they’ve already been approved by Fox for a second season. Word is, terrific merchandising sales on the two soundtrack albums and the first half-season collection of episodes on DVD haven’t hurt the freshman show at all, and played a role in the early renewal.

How well the show will wear over time will be the next big test; NBC’s Chuck was a hot show in its first season and only barely survived to a third season, though it is definitely a welcomed respite from an otherwise dreary NBC lineup this season, now that Chuck is back!

Hopefully, Glee will wear well, and will be wise enough to graduate its cast off the show, and cast wisely their replacements, each and every season. No one wants to see these 22-year-olds playing 15 when they’re 26-year-olds playing 19 and somehow still in high school, like the Sweathogs.
