India, May 7 -- English singer-songwriter Sam Smith is reportedly engaged to boyfriend, English fashion designer Christian Cowan. The couple, who attended the 2026 Met Gala together on Monday, were overheard discussing their engagement before walking the red carpet, as per a report by Page Six. A source from the hotel told the portal, "From what I understand, it was a private engagement. They are over the moon, and from what I hear, so in love!" At the Met, Christain sported a square yellow diamond ring, which has further fuelled the engagement buzz, though there has been no official announcement from either of them yet. Sam, 33, and Christian, 32, were first linked in December 2022 when they attended then-US President Joe Biden's signing of the Respect for Marriage Act at the White House. Since then, they have been spotted together in New York City, accompanying each other to tattoo appointments and fashion shows. HTC...
