Halsey covers on-again beau G-Eazy's white shirt in lipstick kisses at Post Malone's AMAs after party

Earlier at the AMAs, the couple looked totally in love on their first red carpet together since rekindling their romance.

And the passion didn't end there for Halsey, 24, and G-Eazy, 29, with the Bad At Love singer apparently having covered the Me, Myself & I rapper's white shirt in her kisses as the pair arrived at Post Malone's AMAs after party on Tuesday night.

The on-again couple donned matching black and white outfits for the star-studded affair at Harriet's atop of the upcoming 1 Hotel West Hollywood.

Halsey -whose real name is Ashley Nicolette Frangipane- made the most of her gorgeous gams in a black and white checkered shift dress.

She continued the color theme with matching ankle boots.

One of the New Jersey native's few concessions to color was her ever-changing hair, which that evening was cropped short and dyed pink on top, with shaved back and sides exposing her naturally dark roots. 

The songstress wore a vibrant shade of red lipstick - however not all of it remained on her lips, some of the color to having transferred to her boyfriend's otherwise clean white shirt.

Meanwhile, host Post Malone had every reason to celebrate at his AMAs after party.

The 23-year-old Better Now rapper took home the gongs for Favorite Male Rap/Hip Hop Artist and Favorite Rap/Hip Hop Album at the American Music Awards. 

Malone -whose real name is Austin Richard Post- looked dapper in a pink tuxedo for the event.

Kylie Jenner's BFF Jordyn Woods showed off her shapely legs in tiny Lycra shorts.

The 21-year-old model also slipped a sparkling jacket on over a skimpy crop top that showed plenty of Woods' skin.

Jordyn's raven tresses were pulled back in a tight, low pony tail for her night with music industry luminaries.
