Jennifer Garner Reportedly 'Head Over Heels' For boyfriend John Miller After Ben Affleck Divorce

Movie star Jennifer Garner and businessman John Miller are apparently moving pretty fast.

According to an Us Weekly exclusive, published on Wednesday, Oct. 31, 2018, the alleged relationship between the Love, Simon actress and the CaliGroup CEO has reportedly "gotten very serious."

As a source cited by the magazine claimed, Garner is reportedly "head over heels in love" for Miller. 

However, it should be noted that an article published by People magazine on Wednesday has alleged that their blossoming romance is actually bit more casual than previously suspected. "It's not serious, but she enjoys his company," a source told the publication, explaining, "They both have separate families that they are focused on. They see each other when they can."

As Nicki Swift previously reported, Garner, 46, and Miller, 40, were first romantically linked last week when reports surfaced claiming the two had been secretly dating for six months after meeting through mutual friends. "Jen brings out the best in John, and he is the happiest he has probably ever been," an insider told Us Weekly at the time. "It's a loving, healthy relationship."

The dating speculation began just weeks after Garner officially finalized her divorce from ex-husband Ben Affleck. The Camping actress and the Justice League star, who first separated in 2015 after ten years of marriage, share three children together: Violet, 12, Seraphina, 9, and Samuel, 6. Meanwhile, Miller has a 12-year-old son and 10-year-old daughter with his estranged ex, concert violinist Caroline Campbell. The former couple called it quits in 2014, but reportedly have yet to finalize their divorce.

For his part, Affleck is remaining focused on his sobriety following his recent stint in rehab for alcohol addiction. The Oscar winner, who was romantically linked with 22-year-old Playboy model Shauna Sexton this summer after calling it quits with Saturday Night Live producer Lindsay Shookus, was spotted with Garner last weekend at Dodgers Stadium while taking in a World Series game. The former Alias star reportedly met up with her new beau Miller afterward.

"[Moving on] is just a natural step," a source recently told People magazine, adding that Garner "seems very excited about the future." Of the amicable exes, another insider said, "Ben will always want the best for Jen. They both work very hard to make everything easy for the kids."

Now, if only all Hollywood breakups could be this free of drama...
