Aniston was tired seeing her ex-husband Brad Pitt and his new partner Angelina Jolie in the cover of every magazine and she was happy to grab media attention again by flaunting her new figure.
"The reaction from people seeing her in that itsy-bitsy, teeny-weeny bikini did more for Jen's self-image and self-confidence than all her years of therapy put together. She didn't realise the impact it had until she was back in Los Angeles after the trip," an inside source was quoted as saying by dailysnack.com.
"Everywhere she went, everyone she spoke to told her what an absolute knockout she is and what great shape she's in. For a 38-year-old woman who has just come out of a relationship and hasn't been in front of the cameras in two years - it had her walking on air," the source added.
