Lancaster, Stewart to guest on 'Strictly'

Penny Lancaster and husband Rod Stewart will both appear on this weekend's Strictly, say reports.

According to The Sun, former contestant Lancaster will dance, while her partner, 64, sings 'Same Old Song'.

The 38-year-old model will apparently perform a cha cha cha with professional dancer Matthew Cutler.

"Penny is really excited. She's been practising like a demon," said a source. "She's quite nervous. She feels like Cheryl Cole performing on X Factor - hopefully the judges will be as nice to her."

Lancaster competed on the show in 2007, but was knocked out in week six after dancing a salsa.

This weekend's Strictly will be filmed at the top of the Blackpool Tower.
