MAKOSI Musambasi will make a shock return to the UK Big Brother house in a last ditch effort by TV bosses to boost ratings.

Makosi, star of Big Brother six, will return to TV screens on Tuesday to “shake things up in the house”, reports said.

“Producers now want a feisty babe to shake things up in the house - someone with a proven record in stripping, arguing and shagging,” said the Daily Sport in a front page splash.

Viewers slipped from 4.8 million for this year's launch to under two million in the latest episodes.

Channel 4 says as part of celebrations to mark 10 years of the reality TV show, it will bring back six contestants from past series – starting on Sunday when the volatile Big Brother seven star Nikki Grahame returns to perform a task.

Mega-boobed Makosi, 28, will be let loose in the Big Brother house as a surprise “guest housemate”.

A Channel 4 source said: “We need someone who is a proven crowd pleaser, someone who both men and women would tune in to see. We looked back through every former contestant to find the right person, and Makosi was a clear winner.

“She is so outspoken, but men love her because she has got huge boobs and gets them out. She will show Sophie and Karl how it’s done and that’s for sure.”

Controversial ... Makosi liked up for shock Channel 4 return

The former cardiac nurse stunned TV viewers and outraged Zimbabwean conservatives in 2005 when she got locked in a lesbian smooch with Orlaith McCallister. She also claimed she was pregnant after an underwater sex romp with Anthony Hutton.

Makosi declared at the time: “I know what I felt and it was definitely sex. I could feel him up against me and slowly we moved into position until we were having full sex.

“We weren't moving a lot, but we were having sex. Anthony kept asking me if I'd climaxed until I finally did. It was an amazing orgasm.”

She was tight-lipped on Friday and her agent declared: “I can’t confirm anything I’m afraid.”
