Paris Hilton and Kim Kardashian one on one (Video): Intentionally or not, Kim Kardashian has often followed in the footsteps of fellow socialite savant Paris Hilton. Both women have privileged backgrounds, became buzzed-about pop culture symbols, earned notoriety via scandalous sex tapes and parlayed their fame into hit reality TV shows.

Now, Kardashian -- like Hilton before her -- has set her sights on the music world. Last week, the "Keeping Up With the Kardashians" star dropped her first single, the self-released "Jam (Turn It Up)," produced by The-Dream.

In its first five days on sale, the bouncy dance number sold 14,000 downloads according to Nielsen SoundScan. That's not enough to enable a debut on the 75-position Digital Songs chart -- No. 75 this week is Nelly's "Just a Dream," with 26,000 sold.

How does that compare to Hilton's start? The hotel heiress had a more robust bow with her 2006 debut, "Stars Are Blind." The Warner Bros. tune launched on the Digital Songs list at No. 10 with 52,000 in its first week and parlayed those sales into a No. 18 bow on the Billboard Hot 100.

Hilton later went on to release her (so far) only album, "Paris," in August of the same year. It entered the Billboard 200 chart at No. 6 with 77,000 sold in its first week. To date, the set has moved 197,000 in the U.S.
