Bella Hadid and The Weeknd are twinning! (Can you see them, though?)

The two wore camo outfits as part of a party theme as they celebrated the singer's 29th birthday with a private event at the TAO Downtown nightclub in New York City. The venue was transformed into an abandoned, jungle military base, complete with a helicopter installation and overgrown entryway.

Both Bella and The Weeknd wore camo jackets. The Weeknd sported matching pants and Bella, 22, sported a camo crop top and mini skirt, paired with calf-high sheer socks and mustard yellow lace-up booties.

Guests, such as Paris Hilton, who is celebrating her 38th birthday this weekend, also wore camo outfits to the party.

Other guests included Bella's mother Yolanda Hadid, fellow XO artists Belly and Nav, and fellow models Candice Swanepoel, Shanina Shaik and Jasmine Tookes.

Partygoers enjoyed bottles of Rémy Martin and a three-tiered camo cake.

Bella and The Weeknd posted photos of each other.

"1 minute til my favorite day of the year.... @theweeknd," Bella wrote.

A day before the bash, which was Valentine's Day, the Weeknd surprised Bella with more than two dozen containers filled with red roses, worth thousands of dollars.

It marked the first time the Weeknd, whose real name is Abel Tesfaye, and Bella celebrated the holiday of love together since they broke up in late 2016 after dating for a year and a half. The two got back together last summer.
