Hugh Grant and girlfriend Jemima Khan have ended their relationship, Grant's publicist, Robert Garlock, confirms to PEOPLE exclusively.
"Hugh and Jemima have decided to split amicably," says Garlock.
Grant, 46, whose relationship with Elizabeth Hurley ended in 2000, began dating Khan, 33, who has two sons with her ex-husband, cricket-champ-turned-politician Imran Khan, about three years ago.
Grant and Khan were recently together at the London and Los Angeles premieres of his new film, Music and Lyrics.
Last summer, he couple refused to comment on engagement rumors,
but a friend of Khan's told PEOPLE, "He's very clever, and she really is funny, witty and quick. They spark off each other perfectly."
In an appearance on ABC's The View
that aired Friday morning, Grant brought up Khan when talking about how he's become increasingly "fussy" about fashion: "I used to be a man who played rugby and was relatively butch, and now I watch my girlfriend about to go out for the evening and I'll say, 'The brown
shoes, I think.' "
When Barbara Walters noted that he'd been "domesticated" by Khan, whom she described as "pretty attractive and pretty intelligent," Grant said, "I agree with you, I think she's a cracker. She doesn't need my help anyway."
Joy Behar asked, "She's a what?" Replied Grant, "She's a cracker – but that's something different in America."
