Bikini-Clad Jennifer and Shirtless Justin Welcome John and Emily to Cabo

Jennifer Aniston and Justin Theroux lounged under the Mexican sun yesterday in Cabo. Jennifer was engrossed in a novel, while Justin sat close by, thumbing through a script. The pair took a short break from their tanning session to eat tacos and fruit. They also shared an adorable hug and reminded us why they're among the sexiest celebrity couples of 2012. Later on, they had some company! Justin and Jennifer welcomed Emily Blunt, John Krasinski, Jimmy Kimmel, and Molly McNearney to their suite. Emily and John cuddled on a lounge chair, while Jimmy and his wife, Molly, cracked jokes with Jen and Justin.

Jen and Justin arrived in Cabo on Sunday and have since taken to hanging poolside at their tropical resort. The New Year is just around the corner, though still no word on when Jen and Justin plan on tying the knot. Jen and Justin's engagement landed a hot spot on our list of the most shocking moments of 2012, and we can't wait to see what the pair surprises us with in the New Year.
