Is Jennifer Lopez smart to revive romance with Casper?

This came as something of a shocker to a few folks close to Jennifer Lopez: She’s reconnected with ex-beau Casper Smart.

As is usually the case in our social media age, J-Lo turned to Instagram to post a photo of the dancer and choreographer with whom she was linked for almost four years before their split in June 2014.

In her posting, the “American Idol” judge wrote, “#MCM @beaucaspersmart #lovethispic #handsomebear.”

Last month, the reunited couple vacationed in Mexico with Lopez’s twins, a trip that sparked rumors the duo were again romantically involved. Even though Lopez and Smart broke up last summer, the two went out of their way to stress that they had been able to maintain their friendship and the split was totally amicable. Smart was even on the red carpet for the premiere of Lopez’s animated film “Home,” back in March, telling the press, “We’re friends. We’re very good friends.”

Sounds like that’s ramped up quite a bit — yet again.
