Heidi Klum doles out support to pal Christian Siriano

Heidi Klum put aside the drama to support "Project Runway" pal Christian Siriano on Wednesday night.

Klum - who as of late has been subject to rumors that she cheated on ex Seal while they were married - stopped by the grand opening of Siriano's Nolita boutique on Wednesday.

"She was in super good spirits and really happy to be there to support Christian," a partygoer told us about the gorgeous "Runway" judge. "She was talking about the pieces and which ones she loved and wanted."

When Klum left, Siriano, who won the Bravo competition show's fourth season, offered to walk her to her car but she "insisted he stay inside and enjoy his party."
