Jeremy Renner's mystery ex-girlfriend Sonni Pacheco has given birth to their first child, a daughter named Ava Berlin Renner.
Jeremy's rep confirmed the happy news in a statement issued to People.com on Friday (29 March) that read: "They are beyond thrilled. Mother and daughter are doing great."
UsMagazine.com was first to report the child's birth earlier on Friday.
The Avengers star dated Sonni in 2012 and she allegedly discovered she was pregnant after they split. Jeremy, 42, did not comment on the reports when it broke in January this year.
The couple have been living together in Jeremy's Los Angeles home after he apparently agreed to put her up until their child was born.
An insider had said: "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."
The 42-year-old actor was previously overheard telling Eva Longoria he would be a father for the first time when the pair were spotted chatting earlier this year at the Golden Globe Awards in Los Angeles.
It was 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."
