MK & pal at the Pearl Jam concert

According to People, Mary-Kate and Ashley Olsen spent their 22nd birthday in Manchester, Tennessee.

The partying began on June 12 when the tiny twins were spotted in downtown Nashville at a bar called The Wheel. There, they drank diet Red Bull and Patron and listened to the Rob Skaggs Band.

An onlooker from the bar tells People, “They were just having a good time with their friends. Everyone was laughing and dancing. They all seemed very relaxed.”

The next day, MKA hosted a private dinner party for eleven of their friends at the State Room in the Hermitage Hotel, where they were later surprised by Josh Groban. By midnight, the girls left the hotel and went to the My Morning Jacket concert until 3 a.m.

When Saturday rolled around, MKA attended the Bonnaroo Music Festival and caught a glimpse of the Pearl Jam concert. According to onlookers, the girls never stopped dancing from their VIP balcony.

The celebration sadly came to an end on Sunday (June 14) as the girls left their hotel with loads of luggage, a Venti Starbucks and of course, sunglasses!
