USHER - CHILLI COOLS ROMANCE WITH USHER

R+B hunk USHER and TLC beauty ROZONDA 'CHILLI' THOMAS have split.

According to pals, Chilli, 32, has cooled off the romance until 24-year-old Usher decides whether or not he wants to get married and have children.

A source says, "She's fed up with him. Chilli told Usher that if he's not ready to marry her, he could walk - and he did."

Sources tell American tabloid the STAR that the problems stem from the couple's eight-year age difference. Chilli, who has a five-year-old son called TRON with music producer DALLAS AUSTIN, wants to get married and have a child with Usher, whom she has been dating since 2001.

A pal of Usher's notes, "Usher is only 24 and he's not ready for such a big commitment."

Another adds, "They are such passionate people, no one ever knows what their status is. When I talked to him earlier this week, he said they were over. Definitely over. But he's said that before."
