Jeremy Renner has moved his pregnant ex-girlfriend into his home.

The Avengers star - who was overheard telling Eva Longoria that he was going to be a dad for the first time as they chatted at the Golden Globe Awards in Los Angeles earlier this month - is living with the mother of his unborn baby, who has been revealed to be his former love interest Sonni Pacheco from Vancouver.

A source told the National Enquirer that the 22-year-old Canadian model met the 42-year-old actor on the set of his movie Mission Impossible: Ghost Protocol and that Jeremy is "delighted" they are having a baby.

The insider said: "Jeremy is delighted he is becoming a dad.

"He realises it's unconventional to have his baby mama, an ex-girlfriend, living with him and his roommate, but he just doesn't care."

The Hollywood hunk was previously said to be trying to keep the news a secret, including the identity of the baby's mother.

The source explained: "They used to date but it wasn't serious ... [He] is being ultra-secretive about it, but she has been going on about her life and not hiding it."

Jeremy has always aimed to keep his private life to himself, only speaking out about his personal business when he absolutely has to.

The actor was in a four-year relationship with actress Jess Macallan but they separated in 2010 after she decided to pursue an acting career.
