London, Jan 19 : Boxing star Mike Tyson has popped the `big' question to Big Brother star Aisleyne Horgan-Wallace, according to reports.

The ex-world heavyweight champ has proposed to the 30-year-old glamour model and the lady in question has not yet given the answer.

The 42-year-old asked the 30-year-old reality TV star to join him in Los Angeles.

The pair dated before and after Aisleyne's 2006 `Big Brother' stint.

While the model hasn't yet said `Yes', she has told friends that she only sees him as a friend.

"She hasn't ruled it out," The Sun quoted a pal as saying. (ANI)
