Mariah Carey and Jermaine Dupri were at the Guggenheim Museum in Bilbao, Spain, earlier this week, but they weren't there to take in any exhibit.

Rather, the two were on location shooting a video for "Sweetheart," the third single from Dupri's new album, "Life in 1472," and were at the Guggenheim to capture shots of the visually spectacular museum, designed by architect Frank O. Gehry.

As we previously reported (see [article id="1426951"]"Mariah, Mase, Monica, Montell Down For Bay Area All-Star Jam"[/article]), Mariah will make a rare U.S. concert appearance when she performs at the KMEL All-Star Jam on August 29, along with video compatriots Jermaine Durpri, Mase, Monica, Jermaine Dupri and Missy Elliott, among others.
