Derek Jeter & Jessica Biel Caliente.

Looks like Jessica Biel and Derek Jeter may have gotten lucky in Las Vegas over Thanksgiving weekend. The fledgling flames were spied looking "very lovey-dovey" (per People) and "very affectionate" (per Us Weekly) at a variety of Sin City hot spots, even engaging in some tonsil hockey as they hung out at Tryst on Saturday night with Jeter's New York Yankees teammates Alex Rodriguez and Jason Giambi, according to People. Biel, 24, who previously dated "Fantastic Four" comic relief Chris Evans, and Jeter, 32, who has been linked to everyone from Vanessa Minnillo to Mariah Carey, also hit the blackjack tables, where the callipygian cutie made it clear she's already taking advice from the field-playing baseballer.

Her hunch paid off: She won. Mas/More
