Despite the speculation, Lopez said on Sunday that she's still single but not ready to mingle just yet. She said, "I'm single right now, it's really great for me."

Just last month, there were reports hinting that Lopez might also be dating Latin actor and model William Levy.

According to the Latin Post back in December, Levy reportedly broke up with his long term partner Elizabeth Gutierrez so he can free himself up for single mom Lopez.

The site reports that Levy is supposedly so "desperate" to make it big in Hollywood that he is willing to date Lopez to help open up doors for him.

Although both Lopez and Levy have not made any comments about the rumors, the site adds Levy "will be using the attention he gets from this new romance as a stepping stone to achieve his goals."
