The spirit of holiday giving is going full swing in Hollywood. Golden Globe winner & Academy Award nominee Robert Downey Jr., GRAMMY winner Gene Simmons of KISS,  along with Academy Award winners Sean Penn, Mel Gibson, and Jodie Foster join forces to support Mending Kids International next Saturday, December 1st as they take part in the Four Kings & An Ace poker tournament at the London Hotel in West Hollywood, CA.

A limited number of tickets to play poker with the celebrity guests as well as spectator tickets are still available. Event tickets can be purchased here. The tournament will take place inside the Gordon Ramsay restaurant at the London West Hollywood.

The evening proceeds benefit children worldwide who are in need of life-changing surgical care. Over the years, thousands of children have received corrective, transformational surgeries that have given them a chance at longer, healthier and happier lives. Most of the surgeries performed are to correct congenital heart defects, orthopedic abnormalities, severe scoliosis, and significant cranial facial deformities.

Robert Downey Jr has just wrapped filming on MARVEL’s Iron Man 3, due in theaters May 2013 while Sean Penn stars in the upcoming Gangster Squad, due in theaters January 11, 2013.

Sponsors of the evening include Variety, the London West Hollywood, Morgan’s Jeweler’s, Gibson’s ICON films and more.
