Despite their breakup, Ben Affleck and Jennifer Garner seemed to have remained friends and were even spotted together several times after their split.

However, recent rumors claimed that the 43-year-old actor has found new love in the person of 33-year-old actress Sienna Miller.

According to a report by "OK!" magazine, as shared by Gossip Cop, the "G.I. Joe: The Rise of Cobra" actress is allegedly the "Batman v Superman: Dawn of Justice" star's "rebound relationship."

Based on the account of the magazine's source, the "Live By Night" co-stars are "really flirty on set" and Jennifer Garner's ex-husband Ben Affleck even "had Sienna in his sights for a while."

The magazine also claimed that despite the fact that the actor "has remained close to Jennifer Garner since they announced their divorce, a source says he realizes their marriage is in the past and wants to focus on the present - meaning he's ready for a rebound!"

The source continued by saying, "He's not looking for anything serious, and neither is Sienna, so the timing is perfect."

Amid this published rumor involving Ben Affleck and Jennifer Garner, Gossip Cop emphasized that there is no truth to this.

"Ben Affleck is NOT 'eyeing' Sienna Miller for a rebound romance, despite a report," it pointed out. "Gossip Cop can exclusively debunk the claim."

In other news, Radar Online featured snaps of the 43-year-old "Alias" star which accordingly showed off a growing "baby bump."

In the said photos, the "13 Going On 30" star was out with the "Daredevil" actor's mother Christine Boldt.

"The two made their way to church on Sunday, along with Garner's six-year-old daughter Seraphina," the site reported.

Dressed in a charcoal-colored dress, the site noted that she "appeared to be sporting a suspicious bump on their outing."

Ben Affleck and Jennifer Garner are already parents to three children.
