The cast of “Glee” was all smiles today (April 25) as Lea Michele and Cory Monteith made their way from their dressing rooms onto to the set in Los Angeles, CA.

The rumored co-star couple was joined by fellow castmates Dianna Agron and Matthew Morrison with the girls donning matching red and black halter dresses for a performance scene on the hit FOX musical show.

Rounding out the cast members joining in on the midday shoot were Mark Salling, Chord Overstreet, Chris Colfer and Naya Rivera, who also was looking radiant in a red frock.

Meanwhile, notorious bad-girl Lindsay Lohan was also spotted on the set earlier this afternoon for her first guest appearance as a judge at the Nationals competition on the show.

Although she was late, angering Dot Marie Jones, the “Mean Girls” star is apparently enjoying her time partaking in the series and doing quite well.
