Hugh Grant and Jemima Khan reportedly had a curt words at Jemima’s 33rd birthday party earlier this week after Jemima accused Hugh of having a phobia of commitment.

A source at the party held at The George restaurant in Mayfair, London told the Mirror: “The night started off pretty well and they arrived looking very coupley.”

“But when Jemima started chatting to her guests she made a joke about commitment phobia that didn’t go down too well - to say the least.”

Jemima was overheard complaining that Hugh can’t “make up his mind” about anything and that she was annoyed that they were hardly seeing each other because Hugh is busy promoting his new film Music and Lyrics.

The source added: “Hugh didn’t think her comments were appropriate at all. He told her: ‘You’re too overpowering, Jemima. Strong is one thing but you’re behaving like a dictator’.”

“Her comments weren’t intended to upset him but they’d obviously hit a nerve. The mood soured after that and although the couple tried to stay composed for the sake of their guests, it looked like they’d be continuing their row when they got home.”
