Chris Martin must really love his lady…
Well, it's actually a picture of a heart-shaped balloon by allusively famous mystery graffiti artist, Banksy!
The duo, who are rarely seen together in public, were spotted on Saturday night at Sean Penn‘s Help Haiti Home gala—which raised approximately $6 million benefitting J/P Haitian Relief Organization.
The reported painting called Red Balloon started an alleged bidding war between Charlize Theron and Chris, but Gwynie's beau won the pricey $650,000 battle!
And he's not even the celeb that dropped the most dough Saturday night!
The official MC, Anderson Cooper, spent an astronomical $1.4 million for a yet-to-be-created sculpture by Jeff Koons.
Holy gosh darn expensive!
Glad to see these celebs opening their pockets for charity, though!
Ch-ch-check out a pic of the Banksy original (below!)
