David Arquette, Christina McLarty are reportedly expecting a baby

David Arquette is reportedly going to be a father two times over: His girlfriend, Christina McLarty, is said to be in her fourth month of pregnancy.

Arquette, who’s been on and off with “Entertainment Tonight” correspondent McLarty for two years, has allegedly been bragging to friends on set about the baby, TMZ first reported Tuesday. He’s working on a movie in Vancouver, the site said.

A source told Us Weekly that the couple had been trying to keep the news quiet. The pregnancy “came as a surprise,” a source told the mag, adding that the mom- and dad-to-be were both happy.

Arquette, 42, is already father to Coco, 9, his daughter with ex-wife Courteney Cox. Cox and Arquette’s divorce was finalized in May.

It’ll be the first child for McLarty.
