They say that diamonds are a girl's best friend, and Sienna Miller certainly had a twinkle in her eye as she checked out some of the world's most beautiful gems.
The stunning actress was in Los Angeles to unveil a new Valentine's Day competition in the US from luxury chocolate makers Godiva, which is offering one lucky winner a million dollars worth of diamond jewellery, plus a year's supply of chocolate.
The in-demand actress, youthfully radiant in a cropped red jacket teamed with simple black shift dress and Greek-style sandals, appears to have put her difficult split from Jude Law behind her. And these days she is being linked to her Factory Girl co-star, relatively unknown American actor Will Carter.
Having returned from a New Year's break in Kenya, where she celebrated her 25th birthday, the blonde bombshell has now embarked on a whirlwind round of press conferences and parties. She was in Palm Springs for the film festival on Saturday, and was snapped meeting up with Sharon Stone at a party for Bobby in Beverly Hills on Tuesday. On Thursday she'll be making an appearance at a Chanel dinner, before presenting a gong at the Golden Globe ceremony on January 15.
