Although we're sure our favourite celebrities enjoyed plenty of downtime over the holiday period, the glitzy Marquee Nightclub in LA had them out in force for a weekend of New Year celebrations.
At the club's VIP opening, friends Florence and Blake made a sparkling entrance to enjoy a toast or two with fellow guests Beyonce, Solange Knowles and Samantha Ronson.
A staggering number of famous faces including Cameron Diaz and Kirsten Dunst continued to flock to the venue over the course of the weekend, and the star-studded affair culminated in a huge concert featuring Jay-Z, Coldplay and Kanye West. Now that's what we call an A-list party!
But New Year hasn't been the only cause for celebration, as Natalie Portman and Reese Witherspoon have both announced they're engaged.
Reese revealed in the last few days of 2010 that she's set to wed boyfriend of one year, Hollywood agent Jim Toth, who proposed with a 4-carat diamond ring.
Natalie meanwhile announced her engagement to choreographer and model Benjamin Millepied, whom she met on the set of ballet thriller Black Swan. The pair are also expecting their first child.
2011 is sure to be suitably eventful with these two tying the knot!
