UPDATE:
Hugh Grant's rep has released a statement regarding the birth of the actor's daughter, according to E! News.

"I can confirm that Hugh Grant is the delighted father of a baby girl. He and the mother had a fleeting affair and while this was not planned, Hugh could not be happier or more supportive. He and the mother have discussed everything and are on very friendly terms."

It's time for Hugh Grant to break out the pink cigars! The actor welcomed a baby girl last month, Us Weekly reports.

His rep has remained mum on the news and there's no official word as who the child's mother is, but Grant, 51, was last romantically linked to Chinese actress Tinglan Hong back in April.

This is the first child for the actor, who told PARADE magazine in 2009 that he hadn't "given up hope" when it came to one day being a dad.

"Ten years ago, I wouldn't have thought about having children at all," Grant said. "But now I have so many nephews and nieces and cousins and godchildren, I like the thought."

He also mentioned settling down in late 2009, and even included marriage and kids in his New Year's resolutions for 2010.

"I have some resolutions like losing some pounds. I also need to get married and have children," he said while appearing on the Spanish TV program "El Hormiguero."
