Peaches Geldof has announced that she is pregnant with her first child.

The 22-year-old daughter of Sir Bob Geldof and Paula Yates revealed that she was engaged to boyfriend Thomas Cohen last month.

A spokesperson for her said: "Peaches Geldof and her fiancé Thomas Cohen are delighted to announce that Peaches is pregnant with their first child.

"Peaches is utterly thrilled and they have the full support of both of their families who are equally excited for the baby's arrival."

At the time of her engagement, Geldof said that she and Cohen did not want to get married for "a couple of years", adding: "I'm so happy."

Geldof divorced first husband Max Drummey, who she married in Las Vegas in 2009, after just six months of marriage.
