Peaches Geldof knows her baby has chubby cheeks after she saw his face in detail at a 4D scan.

The model-and-TV presenter is expecting her first child with her rocker fiance Thomas Cohen and the couple recently got a glimpse of what their son looks like at the high-tech Ultrasound examination.

Peaches - the daughter of Live Aid co-founder Bob Geldof - insists the baby has the best features of her and Thomas.

She told Britain's HELLO! magazine: ''I'm so excited for the baby's arrival. He looks so beautiful with little chubby cheeks and the best bits of me and Tom. He's going to be a heartbreaker, for sure.''

Excited parents-to-be Peaches and S.C.U.M. singer Thomas are currently busy decorating their new home in London in preparation for the arrival of their son, who they have decided to name Astala Dylan Willow, in April.

The 23-year-old star is getting close to completing the nursery and she can't wait for her little man to enter the world.

She said: ''Tom and I are doing up our new house and garden and Astala's nursery right now in preparation for his imminent arrival and we keep getting woke up by the sound of the builders' floor sander. But it's OK, as we are so excited by how everything is looking in our house and for our baby boy to get here.''
