The Weeknd's Memento Mori radio show is back.

Episode four coincides with The Weeknd's 29th birthday. His model girlfriend Bella Hadid teased the broadcast on social media on Friday, posting a sexy black-and-white video soundtracked by "Lost in the Fire"—The Weeknd's collaborative track with Gesaffelstein. As part of the singer's birthday celebration, Bella teamed up with photographer Alana O’Herlihy to curate a special mix for this week's episode.

"I hope you have a great time listening to my set and just as much fun watching this little video," Bella wrote. "@lilmami_lani and I whipped up for you to enjoy. Happy almost birthday baby."

You can stream episode four of Memento Mori now in Apple Music's Beats 1 radio.

The Weeknd is currently working on a follow-up to 2018's My Dear Melancholy EP. The XO crooner teased the project this past November, telling a Toronto concert audience: "I want you guys to be the first to know that I'm working on my new album right now. Chapter six coming soon. Let's get it."
