Well, Jennifer Lopez's relationship with 24-year-old dancer Casper Smart went from zero to sixty faster than her young beau's whip. Rather than shying away from dating rumors, the American Idol host is putting her romance with dancer Smart on full display, first at an AMA's afterparty, and now in Hawaii, where the pair spent Thanksgiving with Lopez's family, including her twins Max and Emme.

"Casper was great with the kids. He was twirling them around and doing flips with Emme and she seemed very comfortable with him," a source tells Us Weekly. "Jennifer got a chance to sit back and relax while Casper took over and played." According to Radar Online, Smart met several of Lopez's family members during the trip.

Lopez, 42, has tried to be coy about her romance with the backup dancer, telling Ryan Seacrest: "Until I'm in a really serious relationship — because of the babies — I'm not really gonna be commenting on my personal life."

Well, as they say, vacation pictures are worth a thousand words.
