Pump up the "Jam"! Kim Kardashian's first pop single is finally here!

The reality superstar, 30, debuted her song "Jam (Turn It Up)" Wednesday morning during an appearance On Air with Ryan Seacrest.

Kardashian worked with big-time songwriter-producer The-Dream -- the man behind such colossal hits as Beyonce's "Single Ladies, Rihanna's "Umbrella" and other smashes.

Kardashian explained that her pal Ciara hooked her up with the music heavyweight.

"[The-Dream said] let's just have fun. Let’s donate the proceeds, let's just have fun with it don't take yourself seriously, try something you’ve never done before."

She added that she "walked out at one point" during the recording session. "I was scared."
