Janet Jackson has arrived in London to support big sister La Toya ahead of the Celebrity Big Brother final on Friday.

Whilst in the house, La Toya has claimed sister Janet has been an avid fan of the show since their brother Jermaine appeared on it two years ago.

Janet visited the Mahiki club in London on Monday night, where she partied until 2am.

The star is also in town for the launch of Thriller Live, a stage show based on brother Michael's hits and starring ex-Five Star member, Denise Pearson.

Janet is also expected to be backstage if La Toya makes it to the CBB final on Friday night.
