Kim Kardashian's terror at theme park

Kim Kardashian wept with fright after her boyfriend Kanye West took her on a terrifying theme park ride.

The superstar couple took the socialite's younger half-sisters Kendall and Kylie Jenner to the Six Flags Magic Mountain amusement park in Los Angeles on Tuesday (17Jul12).

The thrill-seekers tackled one of the park's fastest rides, but while her entourage grinned with glee, the panic-stricken star broke down in tears.

In snaps uploaded to her Twitter.com account, the brunette beauty is seen crying, while a smiling West tries to reassure her by grabbing her hand.

Taking to the social networking site after the experience, Kardashian wrote, "Magic Mountain fun today!!! Kendall screaming, Kanye laughing & me crying! Mannnn (sic) my crying face! LOL (laugh out loud). I officially am afraid of heights now."
