Perez Hilton shows off weight loss and six-pack on Twitter

Perez Hilton has shared a picture of himself posing shirtless and showing off his sculpted six-pack on Twitter.

The 34-year-old US gossip blogger wore a pair of black boxer shorts while taking the snap standing in front of a mirror in his bathroom in his home in Los Angeles.

Hilton, who has lost around 70lbs since 2008 through healthy eating and working out 7 days a week, added the caption: "I don't know about you, but these new abs I've worked so hard for really do have me feeling 22! Ha."

The star recently revealed he had become a father to a baby boy via a surrogate, whom he named Mario Armando Lavandeira III after himself. 

He posted up to 40 images of his newborn on PerezHilton.com, and gushed: "We are thrilled to formally introduce you all to the angel we are blessed to have as a son, Mario Armando Lavandeira, III Perez Hilton, Jr."
