Kim Kardashian has joined the ranks of single ladies once again!

Hours after news broke of her split from Gabriel Aubry, the reality star and mogul, 30, got back to work at the Whisper Lounge at The Grove in L.A. -- where Kardashian feted the launch of her signature watch collection with the Brissmor company.

Kardashian demurred on talk about sudden ex Aubry, 34, but told UsMagazine.com that she's having "fun" dating.

Best part about not being attached? "My favorite part about being single is just that I can focus on work and not feel guilty," said the star, reportedly the highest-paid reality star of 2010. (TheDailyBeast.com estimated that she netted $6 million between her TV shows, endorsements, her own product lines and appearance fees.)

She and model Aubry -- ex to Halle Berry and father to her daughter Nahla, 2 -- met through friends in October and embarked on a whirlwind romance. The flirty duo stepped out at a Nov. 21 Lakers game, and days later Aubry even joined Kardashian's family for Thanksgiving.

Alas, an insider told Us, things were "moving too fast," and the twosome are "better off as friends."
