Star Tracker: Jennifer Lopez, Marc Anthony, Demi Lovato and more

—Jennifer Lopez and Marc Anthony thrilled fans when they kissed during their performance on a Mexican Telethon. People en Español has the photo.

—The dancer Demi Lovato punched, Alex Welch, has told her side of the story to People Welch says she was taken aback by Demi’s assault and that she still hasn’t received an apology from the young Disney star. Lawyers are involved.

—Enrique Iglesias needs to be more careful the next time he pulls a fan on stage. During his performance at this year’s Jingle Ball concert in New York, he grabbed a fan from the audience to help him sing “I Can Be Your Hero” and the fan was, well, let’s say, colorful. Watch it here.

—On-again, off-again couple Cameron Diaz and A-Rod apparently are still on-again even though E! Online posted a photo of the Yankee with a mysterious woman who was definitely not Cameron Diaz. Apparently he and the woman, a model, weren’t “together together.”
