It looks like Britney Spears' Onyx Hotel Tour will be taking a wicked turn in April.

Wicked Wisdom, a band fronted by Jada Pinkett-Smith, will open for all eight of Spears' U.K. shows, beginning on April 27 in London. The group, which formed about a year ago, frequently plays the Los Angeles club circuit. This will be the band's first major tour.

Wicked Wisdom does not yet have an album out, but those who want to check out Pinkett-Smith's vocals can preview some of their music, including video of a live performance, on their Web site. Among the songs available for listening are the angsty, symphonic rock numbers "Taste Your Fruit" and "You Got To" as well as the sassy R&B ballad "Worship Me."

Though Pinkett-Smith is launching a music career, she'll be keeping her day job. The actress will next appear in the action thriller "Collateral" with Tom Cruise, Jamie Foxx and Mark Ruffalo, due in August. Pinkett-Smith will play an attorney who's on the hit list of a contract killer played by Cruise.
