As Ben Affleck, 46, juggles women and continues alcohol rehab, there's one woman who has remained by his side through it all — and it's not Shauna Sexton!

This Sunday, the recovering addict was spotted arriving in church with ex-wife Jennifer Garner and son Samuel, 6.

The young beauty showed off her bikini body in Malibu, clearly unfazed by her famous man's struggles.

As RadarOnline.com readers know, the two began dating this August after Affleck's boozing became too much to handle for longtime girlfriend Lindsay Shookus.

While Garner, 46, was the one who drove Affleck to rehab and has been checking up on him throughout his time in recovery, it's Sexton who the Hollywood hunk has been spending his bucks on.

"He's a boyfriend with benefits and he likes to share his wealth," an insider told RadarOnline.com. "Shauna isn't asking for this, Ben just loves taking care of her."

And Sexton surely does not seem to mind. This September, she was even caught visiting the hunk at his rehab facility!

While Garner is not a fan of Sexton, she also "not surprised" Affleck has gone back to his womanizing ways after his relapse.
