Premiere/Rocstar/FAMEFLYNET PICTURES Looking good, Justin Theroux!
The 43-year-old actor showed off his hot, muscular, chiseled body during a recent post-Christmas, pre-New Year's holiday with fiancée Jennifer Aniston, 45, in sunny Cabo San Lucas, Mexico. The former Friends star was photographed wearing a dark-colored string bikini top.
Theroux has also appeared shirtless on the HBO post-apocalyptic series The Leftovers, which returns for season 2 in (check out spoilers).
During his and Aniston's trip, the two were joined poolside by fellow Hollywood couple John Krasinski, 35, and wife Emily Blunt, 31, ABC talk show host Jimmy Kimmel, 47, and wife Molly McNearney, 36, and Sirius XM radio shock jock and America's Got Talent judge Howard Stern, 60, who has said on his show that he hates traveling, and his wife Beth Ostrovsky Stern, 42.
Aniston and Theroux and the first three couples have hung out together before. The two actors also vacationed in Cabo San Lucas with Blunt and Krasinski during the same holiday season in 2012.
The two have been engaged for more than two years and four months. Aniston accepted Theroux's marriage proposal on Aug. 10, 2012, his 41st birthday. He proposed with an estimated 8-carat diamond engagement ring.
Before they got engaged, the two actors bought a $21 million, 8,500-square-foot Los Angeles home, which they later renovated.
Aniston's love life has spurred numerous tabloid headlines over the years, but especially in 2014.
"I think I used to really, there was a period where I was hell bent on saying, 'That's not true, that's not right, that's not fair,'" she said in a CBS Sunday Morning interview that airs on Jan. 4. "And now I just think you have to let it roll off your back and you realize, I think everyone knows it's all B.S. and like a soap opera on paper."
Will we see the gorgeous couple walk the red carpet together during the upcoming 2015 award season? Most likely—Aniston received Golden Globe and Screen Actors Guild (SAG) Award nominations for her performance in the R-rated drama movie Cake, one of her grittiest roles. The 2015 Oscar nominations will be revealed on Jan. 15.
