While people were marinating on just what happened at last night's BET Awards, Nelly and Future's performance on 'Arsenio' aired aired as well. The two performed 'Give U Dat,' a rap ballad that's similar to what we heard in 2002's 'Dilemma.' Perhaps the more interesting part about his appearance on the show was the bet he made with Arsenio Hall before his performance.

Nelly, who's a St. Louis native, is a big Cardinals fan. The team is facing off against the Dodgers in the National League Championship Series., so Hall decided to make a wager. If the Cardinals lose, Nelly will return to perform 'Country Grammar' in a Dodger uniform. If the Cardinals win, Hall will do the same with a St. Louis uniform on. We're guessing a lot more people are pushing for the latter for the sake of seeing Nelly perform one of his greatest hits.

Nelly also made an appearance in the comedic 'The Real Husbands of Hollywood' cypher at the BET Hip-Hop Awards, where he spits a few lines while wearing a Versace scarf.

The St. Louis native recently released 'M.O.,' his first album in since '5.0' in 2010. It debuted at No. 14 on the Billboard charts with 14,000 sold in its first week.
