Sam Smith Goes Public With Boyfriend Jonathan Zeizel--See the Pics!

No relationship is official until it's Instagram official!

Sam Smith and boyfriend Jonathan Zeizel crossed that threshold over the holidays, going public on the photo-sharing site with some cute couple-y pics!

The 22-year-old "Stay With Me" singer and his new beau have been vacationing with pals in Sydney, Australia. During their Down Under getaway, both Instagrammed some snaps--including the obligatory #selfie and a silly shot of Jonathan standing on a park bench looking down at Sam.

Perhaps best of all, though, was a picture of Sam and Jonathan recreating Kate Winslet and Leonardo DiCaprio's famous Titanic scene on the bow of the boat. "I'm flying Jack, I'm flying," Sam humorously captioned the LOL-worthy pic.

Last month in an interview with The Sun, Sam revealed he met Jonathan filming "the video for 'Like I Can,' he was one of 20 extras." He told the British tabloid, though, that he and Jonathan's relationship was its "very early days. I'm talking very, very, very early days."

"But he's really sweet," the Grammy nominee gushed.

Sam seems happy with his budding relationship, which is great, but he doesn't want who he dates to be what defines him. He recently explained on The Ellen DeGeneres Show his feelings on the matter, saying, "I want to be a spokesperson for everyone. You know, straight people, gay people, bisexual. I don't want to be limited."

He explained his decision to come out before releasing his album In the Lonely Hour last year, too, saying, "I wanted to do it before, because if I did it afterwards people probably would have thought I was lying just to sell records."

Those closest to him have known he was gay for a long time anyway. "It didn't feel like a coming out. I came out when I was like four years old," he joked. "My mom said she knew when I was like three. So I didn't have to actually properly come out."
