Rejoice!

Amy Winehouse showed up! The Rehab singer made her scheduled appearance at the Virgin Festival in Baltimore on Saturday.

It seems more likely than not that she will make it to Chicago for her Sunday show at Lollapalooza.

Yay!

PerezHilton.com reader Tyler was at Wino’s appearance at the V Festival.

This is what he has to share with you, Perezcious readers:

“She arrived about 5 minutes late and the crowed got restless, but everything was smooth sailing when she stepped up to the mic. The best part was she seemed sober! No slurring, drinking (except a soda can which probably had a little something inside) or obnoxious behavior! She was able to pull her mic out of the wiring and reassemble it in seconds. It was a great performance and her husband was on stage the entire time filming her. It was adorable the way they’d look at each other when she would dedicate a song to him.”
