Rosario Dawson celebrated her brother Clay’s birthday at Mr. H at the Mondrian SoHo on Thursday. The single-again “Trance” star, who recently broke up with director Danny Boyle, was spotted hugging her brother and mom, Isabel Celeste, repeatedly. The party doubled as a karaoke bash for Jamison Ernest’s music label, Brooklyn Beat Records. Scott Lipps, model Linda Vojtova, and Gabe Saporta and his fiancée, designer Erin Fetherston, were also on hand.
