Mariah Carey has extended plans for her world tour, with new West Coast dates set through Dec. 22 in Costa Mesa, Calif. Beforehand, Carey will also visit Shanghai and Manila in mid-November. The artist plays London's Wembley Arena tonight (Oct. 30) and will be in Europe through Nov. 7 in Milan.

Carey's outing got off to rocky start this summer, when a planned arena tour was downgraded to theaters. But the shows have gone off without incident since then and have done solid business; 15 concerts reported to Billboard Boxscore have grossed about $4.2 million and have played to 78% capacity.

The artist has reached out to her fans, allowing them to request songs via her official Web site. Fans can now choose one song ("One Sweet Day," "Love Takes Time," "Vision of Love" or "Can't Take That Away (Mariah's Theme)") to be added each night to the remaining shows.

Here are Mariah Carey's tour dates:

Oct. 30: London (Wembley Arena)
Nov. 1: Manchester, England (Evening News Arena)
Nov. 4: Paris (Bercy)
Nov. 7: Milan (Filaforum)
Nov. 12, 14: Shanghai (Hong Kou Stadium)
Nov. 16: Manila (the Fort)
Dec. 9: Portland, Ore. (Schnitzer Hall)
Dec. 10: Seattle (McCaw Hall)
Dec. 12: San Jose, Calif. (HP Pavilion)
Dec. 15: Santa Barbara, Calif. (Arlington Theater)
