In a romantic move that has Hollywood scratching its head, Jessica Simpson and Orlando Bloom secretly arrived together to Wednesday's Hennessy Artistry event at Paramount Studios.

“They slipped in a little after 8 p.m. and remained backstage for roughly 20 minutes before leaving together,” an eyewitness tells OK!.

The pair popped into the event to catch up with Jess’ little sis, Ashlee, who was there in support of her guy pal Pete Wentz, whose rock group Fall Out Boy was performing.

“Jessica and Orlando are trying to keep their relationship on the down low,” the source says. “It’s all new to them and they’re still just feeling their ways but they are definitely an item.”
