Warning: A date with Nick Jonas may lead to nausea and high pitched screaming!

The youngest Jonas Brother was spotted at Disney's California Adventure yesterday, where he was caught riding the California Screamin' roller coaster with rumored new girlfriend Samantha Barks.

The two have been linked since they co-starred in "Les Miserables" together in London's West End last year.

Nick and Samantha were also seen this weekend grabbing lunch with Nick's brother, Joe.
