I wanna get naughty, says Heidi Montag

London, Jan 18 (ANI): When the 'Celebrity Big Brother' stars noted that Spencer Pratt and Heidi Montag didn't appear to be very affectionate with one another, the couple hit back by saying that they were keeping their hands off each other out of respect for their fellow housemates.

But it seems as though respect might be about to go out of the window as the sexual frustration mounts in 'The Hills' star.

She started to get horny following Lacey Banghard's eviction, fuelled by a couple of beers.

Nuzzling into Pratt's neck, Heidi told her husband she loved him before confessing: "I wanna get naughty, it's been too long!"

And, just to frustrate her even further, Pratt later gave his wife a slap on the bottom, which made her plead: "Again, again! What do I have to do to get more?"

Later, in the bedroom - with all the other housemates in bed except for Rylan, who was washing his pants - the pair's sexual tension went to another level.

Montag asked her grinning hubby if she could roll onto him, before moving closer to him with her hand under the duvet.

"No leg over," Pratt ordered, saying it would be "inappropriate."

And, as the pair did their best to suppress their urges and go to sleep, he told her that she should drink beers more often.

Before going into the house, the pair claimed that they wouldn't have sex on the show - because they hadn't been paid enough to do that. (ANI)
