Hilary Duff
 is embracing her new single status! 

The blonde beauty stopped by Delta Airlines 2014 Grammy Weekend Reception in Hollywood on Thursday -- her first red carpet appearance since separating from husband Mike Comrie earlier this month.

Sporting a super cute printed mini dress and a black blazer, the former "Lizzie McGuire" star looked great (and happy) at the pre-Grammy event. 

One accessory was noticeably missing from Duff's ensemble ... her wedding ring. It's looking like the split will be permanent for the 26-year-old and her hockey player hubby.

Nevertheless, it does seem like the two will remain close friends for their adorable son Luca.

They've been spotted out and about together with their little guy since announcing their breakup, and put out a joint statement via Twitter about their decision.  

Hilary wasn't the only big name at the star-studded event -- click "Launch Gallery" above to see Lorde, Anna Kendrick, Julianne Hough, Lance Bass, Kaley Cuoco and even more of your favorite celebs!
