Hollywood actor Ben Affleck regrets starring in ex-fiancee Jennifer Lopez's music video - because it nearly ruined his career.

Affleck, 35, began dating the Latina singer in 2002 and later that year, he made a cameo in her music video Jenny From The Block. In the promo, the actor can be seen rubbing sun tan lotion onto Lopez's bottom.

In the following years, the couple's high-profile romance proceeded to cross over from the tabloids onto the big screen, culminating in the 2003 box office flop Gigli.

And the Pearl Harbor star is now convinced bringing his personal life into the spotlight was damaging to his career.

He says, "If I have a big regret, it was doing the music video. But that happened years ago. I've moved on."

But Affleck insists he isn't blaming Lopez for his career nosedive: "It not only makes me look like a petulant fool (to blame Lopez), but it surely qualifies as ungentlemanly. For the record, did she hurt my career? No."

The pair became engaged in 2002 but called off their relationship in 2003.
