Gwyneth Paltrow stayed steady in her high heels as she left the Mayfair hotel in London last night — get her gray look here. She enjoyed the evening out to finish her latest jet-setting week. She kicked things off with her turn hosting SNL last weekend and stopped in Geneva for a gala where she looked pretty in pink Alaia. She's been busy promoting Country Strong in recent weeks, and she also got sweet support from Kelly Clarkson who went on her Twitter to plead for Gwyneth to record an album. Through it all, Gwyneth has still been dishing out her weekly dose of wisdom in her GOOP newsletter, though even she admits that every mommy moment isn't perfect.
