Kelly Osbourne spent Thanksgiving in a recording studio with her father Ozzy Osbourne and his Black Sabbath bandmates.

The 'Fashion Police' star's dad couldn't get away from recording sessions with his reformed heavy metal band so Kelly and her mother Sharon decided to join the rockers with a feast of food yesterday (24.11.11).

The 27-year-old blonde admits her dad made up for the unusual dining arrangements by making a delicious sticky toffee pudding for dessert.

In a series of posts on her twitter page, she wrote: "thanx @OfficialSabbath 4 ruining my thanksgiving by staying in the studio u miserable old tea drinkers! ps I'm bringing u food to the studio.

"since its just me and my mum in town looks like we will now be spending thanksgiving in the studio with @OfficialSabbath could be worse :)

"to make up for the fact that my dad was w/ @OfficialSabbath recording he made me the best sticky toffee pudding for thanksgiving dinner! (sic)"

Before having her evening meal with her parents and the band - which also includes Tony Iommi, Geezer Butler and Bill Ward - Kelly was keeping her fingers crossed that her Thanksgiving turkey would be delicious.

She tweeted: "May my turkey be plump and my meal so delicious that my pies take the prize! god please make Thanksgiving dinner Stay off my thighs. (sic)"

Black Sabbath - who initially formed in 1969 - announced they were reforming for a new album and 2012 tour earlier this month.
