Jennifer Aniston showed off her bikini body in Mexico with fiancé Justin Theroux, new sexy bikini pics reveal. You can see the pics here

Jennifer Aniston and Justin Theroux are clearly still madly in love.

Aniston is on vacation with Theroux in Cabo, and the two flirted and engaged in PDAs aplenty.

Jennifer, 44, wore a tiny bikini as she lounged by the pool with Jason Bateman and his wife Amanda Anka.

Theroux, 41, kept kissing her and draped a towel over her shoulders as she got out of the water.

The "We're The Millers" star is relaxing on vacation-and in life. Aniston doesn't plan to get married anytime soon, she says. She doesn't even have a gown yet.

Jennifer looked toned, meaning the recent pregnancy rumors probably aren't accurate either.

Justin and Jennifer want to be "spontaneous" about their wedding...maybe even tying the knot while on vacation in Mexico?

'Jen and Justin have been totally relaxed about the wedding planning... but they have different ideas about the actual wedding itself.

'It's not to do with them as a couple, they're madly in love. Every time you see them they've got their arms around each other.

'Jen wants something bigger with all their friends, Justin would just like something a bit more intimate.'

Aniston and Theroux went to Mexico after a busy promotional trip for "We're The Millers", her latest comedy.

Next on the ticket is yet another comedy-- Life of Crime, which Jen will star in alongside Isla Fisher and Tim Robbins.
