In a pitiful public outburst designed to garner attention and sympathy, singer Jazmine Sullivan abruptly “announced” her departure from the music business last night on Twitter.com — only to take back her announcement a mere 20 minutes later.

With tweets about Ciara and Keri Hilson (not to mention Lil Kim and Nicki Minaj) dominating our timelines, it’s no wonder that other narcissistic celebrities feel a little left out.

Sullivan, who is often confused for singer Chrisette Michele, probably noted that her new album wasn’t moving units and her Twitter timeline was too quiet.

The 23-year-old Philly native took to her Twitter page and tweeted:

“i’m making an official announcement that i am taking a break from music. i’m trying to figure out who i am… w/out a mike, paper or pen. i promised myself when it wasn’t fun anymore i wouldn’t do it. and here i am.”

But it was her next tweet to her thousands of Twitter followers that was most telling:

“i love u all and appreciate u soooooo much,” she added. “…u have no idea how much u’ve inspired me and fed my ego.”

At least she’s honest about Twitter feeding her ego. Other narcissistic celebrities would never admit that much.

These days, attention-hungry celebrities such as Sullivan are bypassing their publicists to feed their crushing egos by creating their own instant rumors on social networks.

The result is posts like this one, with her name in the headline, which never would have been written had she not taken matters into her own hands.

Sullivan’s sophomore album Love Me Back quietly debuted at #17 on the Billboard chart in November, selling a disappointing 57,000 copies in the first week. The disc sold roughly 8,000 units less than her debut CD, Fearless, which dropped in 2008. Fearless spawned Sullivan’s top-ten hits “Bust Your Windows” and “Lions, Tigers & Bears”.
