Jennifer Aniston enjoyed spa days with Justin Theroux and their famous friends on their recent vacation.

The couple - who got engaged in August - welcomed John Krasinski and his wife Emily Blunt and Jimmy Kimmel and his fiancée Molly McNearney to Cabo San Lucas to join them on their post-Christmas trip to Mexico and the former 'Friends' star revealed they all got along so well, they were happy to indulge in beauty treatments together.

Showing off their holiday pictures on Jimmy's talk show, Jennifer said: ''All of you boys were secure enough in your masculinity to join the women on spa day. So the girls had massages, whilst the men were having manicures and pedicures.''

Jennifer, 43, went on to tell the audience that Jimmy made a great holiday companion because he is such an ''amazing cook'', with him and Justin preparing an ''Italian feast'' for New Year's Eve (31.01.12), while all she provided was some ''trailer-trashy ham and cream cheese'' dish.

During her appearance on the show, the 'Bounty Hunter' actress smashed up Jimmy's desk, telling him ''out with the old'' as it was his first day in an earlier time slot, and gave the host a hair cut - the first she had done in 30 years.

Brandishing the scissors, she said: ''I'm so nervous, I'm kind of shaking, I hope that's OK with you.''
