Starting this week, the MTV-sponsored Onyx Hotel tour hits arenas on both sides of the Atlantic. North American venues host the 22-year-old pop superstar through mid-April, then it’s off to the U.K. and Europe, where she’ll make the rounds until June. The tour culminates with an appearance at the festival in Lisbon, Portugal, June 5.

After a two-and-a-half week summer vacation, Spears will kick off the shed tour in Hartford, Conn., on June 22. The current itinerary has her on the road through August 3, when she’ll wrap in Selma, Texas, at the Verizon Wireless Amphitheatre.

Spears released her fourth studio album in November. Like her first three, In The Zone debuted at No. 1.
