Rumors have it that Jennifer Garner and his longtime boyfriend, John Miller, are on the verge of a breakup. Allegedly, their nearing split has something to do with Bradley Cooper.

Jennifer Garner reportedly went to the Academy Awards alone, but she was seen with Bradley Cooper at the event. So, is there really something between the two celebrity friends?

OK! reported the 50-year-old actress was alone at the Oscars because her "romance is cooling off." An alleged source claimed she and her boyfriend are taking things easy and taking a bit of a breather.

As the two just reunited last year after a brief split, it has been said they continued with their on-again-off-again romance. In fact, the insider added that they are not spending much time together as of late.

The tipster continued that they have stopped talking about marriage, which their friends see as a major red flag. They also take not Ben Affleck's former wife's alleged behavior around Bradley Cooper.

She was allegedly seen cozying up to her "Alias" co-star at the ceremony. Another source said her actions are bad for her and John Miller's relationship, even if she was just having fun.

The insider even assumed their relationship seems to be getting re-evaluated with the way Jennifer Garner does not want to commit right now. Of course, Gossip Cop slammed this dubious reporting.

Sure, "The Adam Project" star and Bradley Cooper hung out together, but nothing romantic was going on between them. They have been friends for decades, which is the only thing they have.

They may have done it 20 years ago if they really want to date. Irina Shayk's former partner's rep has also denied these romantic claims.

Also, the latest news about Jennifer Garner and John Miller's relationship is enough evidence to shut down these rumors. The two reportedly hit a major milestone in their romance when their kids finally met each other on the actress' 50th birthday on April 16, per UsWeekly.

A lot of kids and family were invited, including her partner's kids, parents, brother and his brother's wife.

For starters, Jennifer Garner has three kids, Violet, 16, Seraphina, 13 and Samuel, 10, with ex-husband Ben Affleck. John Miller, alternatively, has two children with his former wife, Caroline Campbell.

A source told the publication the couple all had their friends at the vent and the celebration was casual and easy. Jennifer Garner and John Miller started their romance in 2018 and have been reportedly the happiest since.
