The proud mother stepped out in support of her daughter's celebration for being on the cover of an elite magazine.
On May 29, 64-year-old Christie Brinkley was seen on the red carpet at La Pulperia in New York, for the launch party of the new edition of Bella, which features her daughter Alexa Ray Joel on the cover.
In a photo shared by Brinkley to her Instagram account, the model, actress, and businesswoman can be seen showing off her cleancut white outfit.
Brinkley opted for a one-shoulder white shirt, with a long sleeve falling past her elbow. She matched it with a pair of loose-fitting, bellbottomed white pants.
She completed the look with a pair of pointed nude pumps, a white, black, and mustard yellow clutch bag, and a couple of bracelets. She also wore a chunky gold necklace, and left her curly blonde locks hanging loose about her shoulders.
The gushing mama went for a bronzed look with her makeup, and opted for a dark lip color.
Brinkley was also seen snapping shots - still on the red carpet - of Joel holding up the magazine of which she is the cover star.
Joel chose a one-shoulder vibrant print dress with a short hemline for her red carpet outfit. She also opted for a pair of pointed nude pumps for footwear, and left her dark hair falling down her back.
She went for minimal accessories, wearing just a pair of gold hoop earrings and her engagement ring.
Her fiance, Ryan Gleason, was also in attendance in support. The couple first started dating in 2013, and Gleason popped the question in January 2018.
