Jennifer Garner and John Miller have reportedly gone their separate ways. Garner was spotted hanging out with former Alias co-star Bradley Cooper. 

Garner first sparked breakup rumors Wednesday after she was spotted at a beach in Malibu with Cooper. In some photos shared online, the two were joined by the actor's three-year-old daughter Lea De Seine, whom the A Star Is Born actor shares with ex-girlfriend Irina Shayk. 

In the photos, Garner was seen wearing a navy sweater, a patterned skirt, and sneakers. Cooper, on the other hand, went shirtless in reddish-orange swim trunks. The 13 Going on 30 actress seemed to be enjoying Cooper's company. She was seen helping Lea build a sandcastle. 

Us Weekly quoted a source saying Garner and Miller had broke up. The CaliGroup founder was reportedly ready to marry the actress but Jen won't commit. Apparently, Miller wanted to marry Garner but he knows he can't rush the actress. The ex-couple reportedly separated amicably. Garner and Miller have yet to issue a statement.

The pair started dating two years ago. The news that the 48-year-old actress was dating a businessman came weeks after her divorce from Ben Affleck was finalized in 2018. Garner and the Justice League actor ended their marriage in 2015. 

The ex-spouses have three kids that they are now co-parenting. Affleck is currently in a relationship with No Time To Die actress Ana de Armas. 

Earlier this year, Us Weekly reported that Garner was "extremely content and blissfully happy" with her relationship with Miller. The 42-year-old businessman was Garner's support system after Affleck had a relapse at a Halloween party in October 2019.

The two reportedly understand each other on how to raise children after a divorce. Miller has two kids from his previous marriage to Caroline Campbell.

As for Cooper, it has been known that he and Garner have been friends for years since they worked together in the spy thriller series, Alias, which aired from 2001 to 2006. In November 2018, Garner opened up about her long friendship with Cooper when she honored him at the American Cinematheque Awards.

According to Garner, she was one of the first people Cooper met when he arrived in Hollywood. Garner said she took him home and made him dinner.

Cooper and Affleck are good friends. In an interview with The New York Times earlier this year, the Batman actor specifically thanked both Cooper and Robert Downey Jr. for helping him on his sobriety journey. Cooper has been rumored to be dating several celebrities, including Angelina Jolie, but none has been confirmed.
