The 35-year-old singer is rumored to be engaged to Clayton, though neither of them have confirmed the news yet.
Clayton took to his social media page on Thursday (February 4) to share a photo of him and Lana packing on the PDA to celebrate his birthday.
“Happy birthday to me,” he captioned the photo.
The rumors of the engagement started swirling after Lana‘s performance on The Tonight Show Starring Jimmy Fallon in December. During the performance, Lana got fans buzzing on social media when they noticed a big ring on a special finger on her hand. The news of the engagement was confirmed by outlets like People and Us Weekly.
