The blonde beauty - who was a contestant on the reality show in 2006 - is heading back into the famous house and admits she has her "eye on" on model Cristian.

She said: "I hope we're sharing a bed.

"I've had my eye on him. I might tease him a bit - he's gorgeous. The only reason I'd chuck him out of bed is to s**g him on the floor."

The reality star is set to join the show along with two other former housemates including last year's winner Helen Wood, who famously bedded footballer Wayne Rooney.

Nikki shot to fame in the house and became well-known for her dramatic tantrums, including her now famous line, "Who IS she?!' and her romance with 2006 series winner Pete Bennett.

'Big Brother' host Emma Willis first revealed former housemates would be returning to the show when she announced tonight's (12.06.15) fake eviction would see them thrown into a secret lair with the contestant who receives the least public votes.

Meanwhile, Nikki previously claimed she's "mellowed" since her first stint on the show.

She said: "I was a real crazy character, wasn't I? But that was like ten years ago. I had a lot of nervous energy, I've mellowed."
