Jemima Khan and Hugh Grant, according to the Daily Mirror, had a heated dispute at the socialite's 33rd birthday bash on Tuesday.
The pair, who have sparked �baby� rumours across newspapers recently, erupted at each other whilst celebrating at Mayfair�s The George restaurant.
The famously grumpy Grant, 46, allegedly called his girlfriend a �dictator� and a �nag�
The couple had, according to guests, been on good terms until Jemima made jibes at her partner at his lack of ability to commit.
She said, �If I had a child with Hugh, his dad would be 60 even before he was a teenager. That�s how long it takes for Hugh to make up his mind�.
It�s not the first time that the couple have had a public, and heated dispute. In 2005, at Elton John�s lavish White Tie and Tiara Ball, Jemima screeched a torrent of abuse as Liz Hurley, Grant�s ex, seductively sucked his finger!?
Jemima and Hugh have not been invited to Hurley�s wedding to Arun Nayar in India later in the year....
