Usher is bringing some special guests along for the ride on the second leg of his OMG tour. The R&B sensation has announced the opening acts for the North American revival of his tour, revealing that crooner Akon, British rapper Tinie Tempah and party-starting team Dev and the Cataracs will be coming along for the stadium trek.

Akon, whose forthcoming studio album 'Stadium' has been pushed back several times, will remain on tour with Ursh for the entirety of the 21-date venture. Tinie will only appear as an opening act on the first date, while Dev and the Cataracs will hold it down with the Senegalese crooner for the rest of the performances.

The second leg of the successful tour kicks off on April 27 at Ft. Lauderdale's BankAtlantic Center. Throughout the month of May, the collective will make stops at New Jersey's Prudential Center, Detroit's The Palace of Auburn, Orlando's Amway Center and Portland's Rose Garden. The tour wraps up on June 1 at Los Angeles' Staples Center.

The first leg of Usher's successful jaunt kicked off in North America last November, continuing through to Europe in January and Asia and Australia in March 2011. Previous opening acts included Miguel, Trey Songz and Tinchy Stryder.
