The on-again couple were affectionate and low key while partying at Marquee in Las Vegas — until Cam felt A-Rod got too friendly with a waitress!

Cameron Diaz and Alex Rodriguez took advantage of their romantic New Year’s weekend in Las Vegas by hitting up the Boom Box Room at the recently opened Marquee two nights in a row — and getting very close! A source inside the venue said, “Cameron and A-Rod were super low key and spent most of their time talking closely and hanging all over one another.” In fact everything seemed to be going perfect, until Cameron thought Alex got to close to a waitress.

“Alex asked the waitress for a stick of gum, and was incredibly polite, but when she came back to the table Cameron just looked at her and bluntly said, ‘He’s fine,'” says the source.

The source did however confirm the pair are clearly in love and behaved as if no one else was in the club.

The duo was in town for the grand opening of Marquee Nightclub & Dayclub at The Cosmopolitan of Las Vegas, hanging with pals including Gwyneth Paltrow and Chris Martin, Beyonce and Jay-Z and Rihanna. It was back to LA on Jan. 1 however as Cameron gears up to promote her new film The Green Hornet, which comes out Jan. 14.
