BEN'S BRUTAL LOVE TRIANGLE

Caught between wife J.Lo and baby mom Garner

SAD SACK Ben Affleck is caught in a love triangle with ex-wife Jennifer Garner as his marriage to demanding diva Jennifer Lopez shatters, according to sources who say his current wife isn’t ready to pull the plug yet!

“Ben knows Jennifer hasn’t committed to her burger baron beau John Miller yet — and he’s leaning on his baby mom more than he should as things with J.Lo go bad,” an insider tattles. “Months before Ben married J.Lo, he admitted his divorce from Jennifer was his biggest regret!”

The bummed-out Batman, 51, and Garner, 52, announced their split in June 2015 after ten years of marriage. But the exes have remained friendly as they co-parent their kids — Violet, 18, Fin, 15, and Samuel, 12.

Now, sources dish the solace-seeking stud and Garner have been joined at the hip since he gave the 54-year-old Hustlers hottie the heave-ho in March — and the Pearl Harbor hunk has even rented property down the street from the dimple-cheeked Alias cutie.
