At 11.20pm Hugh and Jemima left together in a black cab which had been waiting for them at the end of the street. Jemima was attempting to shield her face with her hands.

Grant has been linked to a string of beautiful women since his split from long-time love actress Liz Hurley.

Grant was reportedly seen emerging from the mews cottage early on Saturday morning and after collecting the papers, he got into his black Mercedes and drove home. Meanwhile, Grant's ex-love, Liz Hurley, who dated him between 1987 and 2001, has reportedly, given her blessings to Hugh's relationship with Jemima.

"Jemima is lovely and I've told Hugh I'm desperate to see him happy and settle down with the perfect woman," she was quoted by the report as saying.


Hugh Grant branded a love rat

Meanwhile, Hugh Grant has been branded a love-rat by his secret Polish girlfriend. Kasia Komorowicz, 30, alleges she dated the Hollywood actor for four-years before he dumped her.

Komorowicz told Britain's News of the World newspaper: "Hugh told me he wanted me to have his babies and I loved him.

But he was just using me for sex." The polish beauty alleges she and Grant, 44, began their relationship shortly after he split from long-term girlfriend Liz Hurley.

They first met in 2000 in London nightclub, 57 Jermyn Street, after Grant gatecrashed her birthday party with a director friend called John.

Komorowicz explained to Britain's News Of The World newspaper: "I held the party in a private area when Hugh strolled in I went up to him and said 'I'm sorry this is a private party, it's my birthday'. He said 'Happy birthday'."

That same night the actor asked his friend to get him her phone number and three days later she agreed to have dinner with him, sparking the start of the relationship.

Komorowicz, who used to work in Geneva in the International Trade centre, claims the couple then saw each other for sex whenever Hugh had the chance. The only occasion the two were ever seen in public was at the premier of Love Actually last November.

Grant and the blonde beauty were pictured, looking happy; kissing and fondling each other but Komorowicz said: "I discovered that Hugh had just used me for a cheap publicity stunt at the film premiere before cutting me out of his life."

Komorowicz said she had hoped Grant would be her dream man but instead turned out to be just like love-cheat 'Daniel' from the film Bridget Jones' Diary. Komorowicz said: "With me he was just like the guy he plays in Bridget Jones' Diary - he really knows how to seduce, satisfy and ultimately con a woman. His whole life is an act."
