Here's further proof that Jennifer Aniston is definitely not pregnant (despite the "insider" reports in glossy mags every week).
The 43-year-old actress showed off her taut tummy and extremely toned fiancé Justin Theroux on their Christmas holiday in Mexico's beachside getaway spot Cabo San Lucas.
While Jen has always kept herself looking super-fit, we had no idea that Justin, 41, had such a tight six-pack or so many tattoos. Watch the video above for all the pics and don't beat yourself up over eating too much Christmas turkey.
Jen heads to Cabo San Lucas this time every year, and she's expected to see in the new year in the resort town.
There's no word yet on the couple's wedding date, but the pair reportedly held an engagement party earlier this month at their Beverly Hills home.
