Eat, pray, birthday?
As she marks her 50th birthday on Sunday, Demi Moore
is coming off a festive trip to India, where she and several close friends – including L.A. florist Eric Buterbaugh – were among the 150 guests at an extravagant birthday party for supermodel Naomi Campbell's Russian billionaire boyfriend Vladimir Doronin.
The actress was photographed at
the Jodhpur-based bash wearing a traditional ghagra choli by Indian designer Manish Malhotra.
Sources say Moore has since jetted to Dubai.
The half-century mark is a significant one for Moore, who is leaving behind an exceptionally difficult year: Her six-year marriage
to Ashton Kutcher
, 34, ended last November
, and two months later Moore underwent an emergency hospitalization
amid friends' concerns for her physical and mental health.
"She was struggling, and she was sad," a source recently told PEOPLE. "There were things she had to work on."
Since then, the former Brat Packer has maintained a low profile, even as her ex revs up his romance
with actress Mila Kunis
Although Moore has long positioned herself as one of Hollywood's most age-defying beauties – she recently indulged in a B-12 shot and a facial treatment at the Cryohealthcare Clinic in Beverly Hills and promoted the beauty line Oriflame in Sweden – the actress is not stressing about her big birthday, an insider recently told PEOPLE.
"She's not unhappy about turning 50," said the source. "She looks beautiful and is feeling good after a really, really tough year."
