Nelly may have been pretty quiet on the music front recently but he made his prescence felt during his 37th birthday celebrations on Saturday, hitting up TAO in Las Vegas after watching boxer Manny Pacquiao fight at the nearby MGM Grand.

The multi-platinum rapper occasionally left the confines of the VIP area to rock a packed crowd inside the club, running through live performances of  'Hot in Here' and 'Where Da Party At'.

Nelly also hit the stage last week to join Taylor Swift on her Speak Now tour show in Houston, surprising the crowd with a performance of 'Just a Dream'.

Notably absent from his birthday celebrations was his rumoured girlfriend Ashanti.
