Los Angeles, California - Selena Gomez gave a "nostalgic" nod to her ex-boyfriend, Nick Jonas, in a new TikTok!

The former Disney darling took to TikTok on Thursday to share another peek at her look from the Fourth Annual Rare Impact Fund Benefit, which honors her mental health charity.

The red-hot strapless gown, designed by Prada, featured embellishments throughout and a peplum-esque structured waist. She completed the look with matching red pumps.

After showing off the number at Wednesday's event, Selena dropped a new TikTok video set to none other than Burnin' Up by the Jonas Brothers – specifically the fan-favorite line where Nick shouts, "Red dress!"

Sydney Sweeney Sydney Sweeney's raunchy sports betting ad slammed by MLB star: "Parents shouldn't have to worry about this"

"Feeling nostalgic," she wrote in the caption.

Naturally, the video had Gen-Z totally in their feels.

"The song choice is so important to me," one fan wrote alongside a photo of the pair from their Disney Channel days, while another wrote, "I fear no one is understanding how iconic this is."

And Selena and Nick weren't just colleagues on Disney – they even dated on-and-off between 2008 and 2010!

Alas, the video – which now has over 15 million views – isn't exactly Selena shooting her shot at a former flame.

Both she and Nick are happily married: Selena tied the knot with music producer Benny Blanco last year, while the Jealous singer has been married to actor Priyanka Chopra since 2018.
