Ariana Grande -- MTV Movie Awards 2010

Ariana Grande brings some bling in Herve Leger to the red carpet as she arrives at the 2010 MTV Movie Awards held at the Gibson Amphitheatre at Universal Studios on Sunday afternoon (June 6).

While the 16-year-old starlet had a blast at the award ceremony — she loved Katy Perry‘s performance and was happy Zach Galifinakis won — she skipped the after party and headed straight to the studio.

Ariana tweeted, “Missing the afterparty to go unto the recording studio for the rest of the night! …I’m pretty sure I’m on my own time zone. Haha. ;)”

We can’t wait to hear Ari‘s new stuff!
