Are Heidi Klum and Seal the rudest couple around?

The two blew off Elton John in a big way on the night of Elton's Aids Foundation Oscar party on Feb. 25. "Audi sent a car to pick Seal and his plus one up," says the source, who notes that the plus one was expected to be Heidi. "But Seal kept the car waiting for four hours. He kept delaying. Then it started to get really late and everyone was like, 'Where's Seal?'

"There was a spot for him at the President's table and it was noticeably vacant. Seal had total VIP for everything because he's done work for one of the sponsors, Audi, so everyone thought he'd be there for sure. But he was nowhere to be found. He either took the car to another party, was hiding in the bathroom or was still at home with Heidi and the kids."

Good thing another singer, James Blunt, was there to liven up the crowd with an outstanding performance!

Meanwhile, a solo Victoria Beckham, one of the first guests to arrive, was wearing a long, white dress by designer Alia. When asked what the tattoos on her upper back meant, Posh told Star, "They are Hindu symbols." Victoria also expressed her concern for Britney Spears. "I wish her all the best, my prayers are with her," she said.
