Late last week Nicole turned the big 3-0, and what better way to celebrate than a girly weekend away in Mexico with your bestest friends!
On holiday with Nicole included Katherine Power, Masha Gordon, Samantha Ronson, Jessica and Ashlee Simpson.
So far Nicole has been spotted on the beach and in her hotel pool in two different bikinis.
Both times Nicole looks incredible! Is it just me or is her gym routine paying off so much, she looks very fit and healthy to me :)
Nicole was also spotted out for lunch with the Simpson sisters and Ashlee's bf.
Which of Nicole's bikini's do you prefer? Blue or Black?
