Is Ben Affleck a fan of Flipper?

Jennifer Garner's hubby and dad to daughters Violet, 4, Seraphina, 2, and a new baby-to-be on the way, inadvertently revealed a dolphin tattoo on his right hip Saturday when his shirt rode up as he fastened his daughter into a car seat.

Another fan of dolphin-themed body ink? Affleck's newly-single ex-fiancee Jennifer Lopez. The 42-year-old American Idol judge has a similar marine mammal tattooed on the back of her right shoulder.

Although Affleck, 39, and Lopez famously called off their engagement and 18-month romance in January 2004, sources told Us Weekly that when the singer-actress' 7-year marriage to Marc Anthony was falling apart, Lopez's mom Guadalupe Lopez went to Affleck for advice.

"Guadalupe reached out to Ben over email. She wanted advice for Jennifer," revealed a source, adding, "She always liked and trusted him. [Ben] replied back on email, wished her well and offered what he could."
