BUSTY Daniela Roffey knows first-hand about BB favourite Rodrigo Lopes being bisexual - she went to bed with him and a FELLA joined in!

All three were part of a group put in the house to test it for the last Celebrity Big Brother - and they certainly gave the mattress a thorough going over.

But Daniela, an investment banking assistant, was disappointed to discover that Brazilian Rodrigo, 23, had a Little, ahem, Brother.

And she warned that despite his sweet persona, he could suddenly fly into unprovoked rages.

Daniela, 25, said: "Everyone thinks he's like a clean-cut hunk from High School Musical but the reality couldn't be be more different.

"He'll crack soon and viewers will see the real Rodrigo."

Curvy Daniela was asked to try out the house after narrowly missing out on a place in last year's BB. She fell for Rodrigo instantly.

She said: "There were 12 of us-some who hadn't got into BB9, others were potentials for BB10. I thought Rodrigo was gorgeous-like a better-looking Cristiano Ronaldo.

"But I thought he was really camp, and at one point I said to him: 'Are you gay?' He was really shocked and said immediately he was straight."

The pair started flirting and on their first night Rodrigo asked Daniela to share his bed. But as things got steamy, a gay 19-year-old housemate called Tommy joined them.

Daniela, from London, said: "I was in a tiny see-through camisole and G-string, and Rodrigo couldn't keep his hands off me. We stopped just short of having full sex but things got very sexy.

"Then suddenly Tommy lifted the covers and slipped in with us. I was sure Rodrigo would tell him to get out, but he welcomed him into our bed on the other side of him.

"Rodrigo carried on touching me and I thought Tommy was just enjoying being there alongside us. But soon Rodrigo was giggling with Tommy too. Talk about having your cake and eating it."

The next night Daniela was shocked when Rodrigo yelled insults at her. She said: "As a joke, a few of us started banging on saucepans because some of the housemates were keeping us up.

"Rodrigo turned on me. 'You're nothing,' he raged. 'You may be beautiful, but you're ugly on the inside.' He was shouting and swearing at me. His face was so red he looked like he was going to explode. I burst into %+!$@ and ran into the Diary Room.

"When I came out, he apologised.He's a Jekyll and Hyde character." After their three-day stint in the house, Daniela met up with Rodrigo for a night of passion in a hotel. She recalled: "But when I took off his boxers I was really gutted. He had the smallest manhood I have ever seen. But he didn't seem embarrassed.

"Despite his shortcomings, I really fell for him."

They phoned each other for a month, then in January he told her he was returning to Brazil. The next time she saw him was on TV. She said: "Rodrigo will play the game but it will be a stormy ride. Those housemates can consider themselves warned."
