Singer Lance Bass is heading down the aisle after proposing to his boyfriend.

The star popped the question to aspiring actor/model Michael Turchin during a trip to New Orleans, Louisiana for America's Labor Day holiday weekend (30Aug13-02Sep13) - and his beau said yes.

A source tells, "They're such a great couple, everyone is so happy for them. Their friends and family are thrilled."

Bass has yet to confirm the engagement, but Turchin hinted at the big news on Saturday (31Aug13) when he took to to write, "Happiest guy in the world".

The proposal will give Bass another reason to celebrate following his brief reunion with his former 'N Sync bandmates at last weekend's (25Aug13) MTV Video Music Awards in New York.

The singer, who announced he was gay in 2006, began dating Turchin in December, 2011.
