Lady Gaga in Thanksgiving special on ABC television

Lady Gaga
The star adds an extra verse to White Christmas during the special show

Lady Gaga is to appear in a Thanksgiving Day special in front of friends and family on Thursday night.

The star will perform eight songs on the American TV programme, including her own version of White Christmas.

A leaked online version of the song seems to show she has added her own extra verse to the classic song.

The 90-minute show will also feature an interview at Gaga's former school and see the 25-year-old cook turkey and waffles for the audience.

Other songs in the special show include her latest single, Marry the Night, You and I and Edge of Glory.

Tony Bennett, who worked with Amy Winehouse before her death, will also duet with Lady Gaga on The Lady is a Tramp.

The festive theme of the show also sees the star take on the classic song White Christmas.

In an unverified leaked clip on YouTube, she is heard saying the song is "too short" and adding an extra verse.

She sings: "I'm dreaming of a white snowman, with a carrot nose and charcoal eyes.

"And when he cries I'm going to tell him it's alright, 'cause Santa's on his sleigh and he's on his way."

Lady Gaga also directed the Thanksgiving Special, which is being aired on the ABC network.

The star told the network her own festive traditions were surprisingly normal.

"I just love to be with my family," she said

"I just love to eat all day long with my grandma and watch old movies and talk about the year."
