Word is, things aren’t looking good for cougar Jennifer Lopez and her cub, Casper Smart. The pair attended the Human Rights Campaign national dinner on October 5 in Washington, D.C. where J. Lo was honored…but were sure not to be photographed with each other, and didn’t even walk the red carpet together! In fact, they haven’t been photographed together in public in more than three weeks! “Jennifer is pretty private about the relationship, but she’s been hinting that the spark is gone,” a source close to her said. “She’s having a hard time ignoring the fact that her head has been telling her for a while that this thing with Casper isn’t forever. And now her heart’s saying the same thing. They’re obviously in very different places in their lives, and Jennifer wants to take responsibility for her life and not repeat the same mistakes she has made in the past. She enjoyed the relationship for what it is, but now that giddiness has turned to sadness.” Time will soon tell! These two seemed to have an expiration date on them from the start, so this doesn’t really come as much of a surprise.
