Let the good times roll!

When it came time to fete her 28th birthday, Mandy Moore skipped the fancy restaurants and exclusive nightclubs, and headed to the roller rink instead.

After a laid-back birthday meal, the Tangled star--who officially turns the big 2-8 on Tuesday--got her skate on at The Moonlight Rollerway in Glendale with a small group of friends, including her husband of three years, Ryan Adams, and pal Minka Kelly.

"They had a small table which was decked out with birthday balloons and flashing lights," an eyewitness tells Us Weekly of the casual celebration. "She was a good skater! They were there for a few hours on Saturday night and just blended in with the local crowd."

Adds the witness, "Mandy was laughing with her friends as they went around the rink, trying to dance to the music. They all seemed to be having a good time."

Post-party, the ecstatic birthday girl took to Twitter to thank her pals for helping her celebrate. "I have the best friends," Moore wrote. "Thank you...for making the bday party evening a reality! Such a blast!!"
