American pop star, Christina Aguilera, shows up in Shanghai before her Tuesday performance at the Shanghai Grand Stage, on Monday, June 25, 2007.

American pop star Christina Aguilera says "it's very exciting" to be in China.

The four-time Grammy-Award winner met with the media on Monday, ahead of her first Chinese mainland concert on Tuesday night at the Shanghai Grand Stage, where she will sing for an audience of 8,400 people.

"It's very exciting for me to be here," she was quoted by AFP as saying.

The singer's "Back to Basics" world tour has taken her to meet fans in the United States, Europe, Japan and South Korea.

Aguilera is the latest international star to perform at the venue, following Roger Waters' show early this year, and the Rolling Stones' visit last April.
