Bob Geldof's daughter Peaches has escaped the winter chill in Britain and headed off on her honeymoon, four months after marrying Thomas Cohen.

The socialite, who is pregnant with her second child, exchanged vows with rocker Cohen in September (12), but they only managed to get away and enjoy the traditional romantic vacation on Tuesday (22Jan13).

Peaches shared a number of photos from their sunny destination via on Wednesday (23Jan13), but did not reveal where they had chosen to holiday.

The 23 year old also told fans of her struggle to spend time away from their baby son Astala, who was born last April (12).

Showing off an image of her kissing a cute picture of her boy, she writes: "Me at the airport yesterday missing Grublet who is staying at his grandma and grandpa Cohens for the few days we are here! Going to facetime (video chat) with him tonight miss him loads".

Peaches Geldof announced she was expecting another son in November (12).
