Gwyneth Paltrow plays Holly, a substitute teacher who takes over when Mr. Schuester gets sick in this week’s episode of Glee.

But it seems not everyone is happy to see Miss Holiday taking control.

Will’s wife Terri (Jessalyn Gilsig) asks if she is a “porn star or a drag queen”, while Sue Sylvester (Jane Lynch) tells her “berets are out”.

More notes from the show…Glee star Kevin McHale was seen making his first ever public singing performance in a video shown on TV.

The home video footage of McHale as a youngster singing at his sister’s wedding in Texas was shown by talk show host Jay Leno.

McHale, who plays wheelchair-bound Artie, told Leno that he had sung tunes from the Lion King for guests at the wedding.

Leno then played a music video McHale, 22, had made while a teenage member of the boy band NLT or Not Like Them.

McHale started the interview by reminding Leno his sister used to work on the Tonight Show and that Jay used to let him in the studio to listen to the band warm up.
