'Twilight,' 'High School Musical' Stars Help Reopen Guess Store: See Pics

You'll never guess who was at the store on the Tuesday.

From 7 to 9 p.m., Twilight's Christian Serratos, High School Musical 3's Matt Prokop and an array of other stars dropped by for the grand reopening of the store. They were clad in Guess clothes, of course.

The reopening doubled as a publicity and charity push for the Art in the Streets graffiti-and-street-art exhibit on display at Los Angeles' Museum of Contemporary Art. Fittingly, the clothing store featured a wall with live graffiti painting and art installations, courtesy of Tiffany Trenda and The Bumbys.

Ten percent of sales from the night went to MOCA.

Other attendees included Prokop's girlfriend, Sarah Hyland of Modern Family; Esme Bianco of Game of Thrones; Tiffany Thornton and Sterling Knight of So Random!; Zack Lively of Greek; Beth Behrs of Two Broke Girls; Claire Coffee of Grimm; Madeline Zima of Californication; and Scottie Thompson of Skyline. 

Models Jaimie Hilfiger and Krista Mills were there as well, and Guess co-founder Maurice Marciano made an appearance.
