When we heard that 'Glee' was celebrating its upcoming 300th musical number with a special diva mash-up, we could hardly contain our excitement. We all have our own personal favorite numbers from the show, but seeing what's to come between now and milestone number 300? Well, there are just too many musical possibilities there not to get our minds into full casting mode.

In honor of the show's return (Tues., Nov. 1, 8PM ET on Fox), AOL TV decided to offer some free advice to the showrunners -- we mapped out who should sing the tracks leading up to lucky No. 300, laying out some possible new plot points as well.

We already know some of the answers, but for the rest we used our encyclopedia of 'Glee' knowledge to recommend the optimal vocalists for each upcoming track. Take a look ...

Gleeks, say hello to McKinley High's latest heartthrob: Rory Flanagan, played by 'The Glee Project' winner Damian McGinty.

Fans of the Oxygen reality competition show swooned over the 18-year-old former Celtic Thunder singer, partly because of his dreamy Irish accent, but mostly because of his adorably clumsy footwork and his velvety smooth voice.

Next week's 'Glee' (Tues., Nov. 1, 8PM ET on Fox) marks the much-anticipated arrival of McGinty as McKinley High's new Irish foreign exchange student, but he's not exactly receiving the warmest welcome.

"Rory is very sweet and really innocent, and it's kind of sad because he wants to fit in and he always has a smile of his face, but he's just getting continually bullied," McGinty told us. "He's getting thrown off lockers and pushed into lockers. It's quite sad. He just wants friends and for people to like him." See? Adorable.

I got a sneak peek at a diva-licious 'Glee' number today -- the show's 300th performance -- and can share some spoilery details with you here, if you're curious.

And 'Glee' fans, I know you're curious.

Take a peek after the jump to see what Mercedes, Santana and another soon-to-be-ex-New Directions member are up to for the big number, which we won't see until the Nov. 15 episode...

As resident McKinley High troublemaker Santana on 'Glee,' supporting actress Naya Rivera routinely steps aside for series standouts Lea Michele, Chris Colfer and Santana's love interest, played by Heather Morris, to take the spotlight.

But now, the 24-year-old Californian is making a play for solo success: EW.com reports that Rivera has scored a record deal with Columbia Records.

Rivera is the third star of the hit series to go solo. 'Glee' castmates Matthew Morrison (Will Shuester) and Mark Salling (Puck) have already released their own albums -- while many fans of Broadway belter Michele remain hopeful she'll announce a record deal soon.

While portraying the Cheerios villain whose role grew substantially in season 2, Rivera has been a versatile vocalist on 'Glee,' rocking covers from ABBA to Amy Winehouse. But there's no word yet on the musical style she'll aim for when she enters the studio for her debut album.

It was bound to happen: 'Project Runway' will have an all star season.

Lifetime will have eight one-hour episodes of the season with veteran designers. Last time 'Project Runway' assembled past contestants was for the 2009 'Project Runway All Star Challenge.' Season 2's Daniel Vosovic won the 'All Star Challenge.'

In addition to season 9 of 'Project Runway' and 'Project Runway All Stars,' Lifetime has also announced 'Project Accessory.' The new series will follow artists as they attempt to create the newest trend in accessories.
