Jeremy Renner and his ex-girlfriend, Sonni Pacheco, welcomed a daughter on Thursday.
The two-time Academy Award-nominated actor has yet to announce the birth of his first child because the Avengers star is being "ultra-secretive about it" according to a report.
While Renner chooses to remain private about his personal life, a source told Us Weekly that the ex-girlfriend "has been going on about her life and not hiding it."
Since the news was published on Friday, fans of the actor are asking in social media: who is Renner's ex-girlfriend?
National Enquirer revealed in January that the mother of Renner's child is twenty-something Canadian model Sonni Pacheco who hails from Vancouver, British Columbia.
According to the report, Renner met Pacheco on the set of Mission Impossible: Ghost Protocol. A friend told the newspaper that the actor spent quality time with the model when he started working on the following movie, The Bourne Legacy.
"When Jeremy returned to Vancouver to film 'The Bourne Legacy,' they hooked up again and started staying together at the same hotel," a friend told National Enquirer.
Pacheco has been a spokeswoman for Monster Energy drink and provided background details about herself on the company's website, which has since been taken down.
"I grew up on a farm, catching frogs and doing boyish stuff, so I could definitely have been called a tomboy," she wrote according to a report. Pacheco wrote that she grew up in Pitt Meadows, B.C., sold timeshares at a Mexico hotel resort for a few months and has worked in China as model.
In addition to working on the Mission Impossible sequel as a stand-in, Pacheco has another film credit on her resume for the straight-to-video movie American Pie Presents: The Book of Love where she played the "Splendid Wet T-Shirt Girl."
Us Weekly reported in January that sources overheard the Borne Legacy actor telling his good friend, actress Eva Longoria, that he was going to be a father.
The Hollywood stars were attending a Golden Globes party at the time he shared his good news with the Desperate Housewives actress. He said that he was going to "fly in when (her) water breaks," a source told Us Weekly at the time.
