Chris Brown and Rihanna were the very picture of a couple in love at the Grammys on Sunday, yet totally ignored each other at a Hollywood club later in the week.

Kids. Whaddaya gonna do.

According to a source, the pair arrived separately, left separately and didn't once acknowledge the other's existence at the Playhouse Nightclub on Wednesday night. What's worse, when the club's VIP hosts asked if Rihanna would like to be seated with Brown (whom she reportedly didn't even know would be there), she pointedly asked to be placed elsewhere.

“Rihanna refused to sit with or even near Chris – and when Chris noticed [her], he made a huge show of rubbing his presence in her face," the insider claimed.

"He promptly ordered three more bottles of [Ace of Spade champagne] which came out with a procession of sparklers and scantily-clad cocktail waitresses, causing a spectacle, which he clearly wanted Rihanna to see."

While Brown surrounded himself with his 20-person entourage, Rihanna brought along some beefy bodyguards to keep her company. He left around 2 a.m., and she didn't depart until about an hour later.

If you're hearing a high-pitched sound right now, it's cool. That's probably just Katy Perry off somewhere squealing with delight.
