NEW YORK -- Breakout rap star [artist id="2545682"]Drake[/artist] appeared on "The Tonight Show With Conan O'Brien" on Friday, performing alongside [artist id="7590"]Jamie Foxx[/artist]. The "Best I Ever Had" MC premiered his guest verse on Foxx's track "Digital Girl."

In recent weeks, Drake -- who is still unsigned -- seems to be everywhere, performing at [article id="1613406"]Hot 97's Summer Jam[/article] concert, flying to London to [article id="1613117"]collaborate with Rihanna[/article] and now making his late-night-television debut next to an Oscar-winning actor.

But the [article id="1612955"]Lil Wayne protégé[/article] took everything in stride. Or, rather, with a bit of anxiety. Drake had just recorded the remix less than 24 hours before he went before millions of TV viewers with it.

"The biggest challenge of that whole day, aside from being on 'Conan' and being nervous initially about that, was [trying to] remember the 24-bar verse I just recorded the night before," Drake told MTV News. "It was an all-around challenging day, but when I'm under pressure, I always seem to rise to the occasion in some form."

The rapper, who exploded with the release of his mixtape So Far Gone in February, said the appearance marked one of the best days of his life.

"My uncle saw it, my mother saw it, everyone in my family and in my circle was so excited," he said. "It was something I'll never forget. I don't think an unsigned artist has ever had the chance to perform in that arena."

Next up for Drake is finishing a [article id="1612424"]video for his hit "Best I Ever Had."[/article] The rapper was in New York over the weekend filming the video with Kanye West. West inspired the clip, according to Drake, and eventually took the reins as director of the shoot. Also, Drizzy will join Lil Wayne and Young Jeezy on their [article id="1613926"]America's Most Wanted Music Festival[/article], which kicks off July 27 in Scranton, Pennsylvania.
