Amanda Crew shows off her muscles with gal pal Amber Borycki as they attend the Muscle Milk Light Women’s Fitness Retreat in Beverly Hills late last week.

The 24-year-old Charlie St. Cloud actress told JJJ that she actually had butterflies the first couple times she had to kiss costar Zac Efron.

But don’t fret — Amanda also told us that after a couple of days, it was just another day at the office.

Charlie St. Cloud hits theaters on July 30th.
