Lil Wayne On Performing With Chris Brown: 'U Kno I Had To Show Him Sum Luv'

Brown made a surprise appearance at America's Most Wanted tour stop in Virginia.

[artist id="510062"]Lil Wayne[/artist] fans got a big surprise when the America's Most Wanted tour rolled into the Verizon Wireless Amphitheater in Virginia Beach, Virginia, two nights after Drake was forced to leave the tour after seriously re-injuring his knee.

That surprise was a guest appearance from [artist id="1961441"]Chris Brown[/artist].

In his first onstage appearance since pleading guilty to assaulting Rihanna

in February, singer Chris Brown jumped onstage near the end of headliner Lil Wayne's set. Brown, who is from Virginia, helped out by lending his voice to Drake's "Every Girl," and paid tribute to Michael Jackson by Moonwalking and busting some classic MJ moves

as "Billie Jean" played in the background at the end of the night's show. Wayne asked the crowd to make noise for "the new Michael."

When asked by MTV News for a comment about the performance, Weezy responded simply via e-mail through a rep: "U kno I had to show him sum luv."

The surprise appearance at the Young Money gig was Brown's first public appearance since releasing a video on July 20 in which he apologized to Rihanna for the assault on the eve of the Grammys, which left her with facial contusions and cuts. Brown pleaded guilty last month to one count of felony assault and was ordered to perform 180 days of community service in Virginia as part of his plea deal.

At press time, and it was unclear if Brown will be performing on other dates on the tour,

which is scheduled to last through August 23. Brown appeared to be trying to fill a gap created when Drake went down on Friday night at a show in Camden, New Jersey, where he re-injured his already torn up knee, requiring immediate surgery. Drake blogged about being laid up over the weekend.
