Heading out for an exclusive bash at the private Mark's Club in London, Gwyneth Paltrow showed up in style on Tuesday (May 21).

The "Iron Man" star wore a short white patterned dress with buttons on top, a black clutch, and black strappy sandals as she made her way inside.

Just the day before, the 40-year-old actress joined hubby Chris Martin and their children Apple and Moses for a family outing.

Holding her 9-year-old daughter's hand, Gwyneth strolled along the streets of London with a bright smile on her face.
