Congratulations to Lady Gaga who is engaged to her long-term partner Taylor Kinney! The pop star and her actor boyfriend got engaged on Valentine's Day, before celebrating with Gaga's family in her father's Italian restaurant in New York City.

Gaga stepped out in New York City on Monday and coyly kept her ring finger hidden, but she couldn't keep the large smile off her face.

She later posted a snap of the ring - a stunning diamond-encrusted heart-shaped ring - on Instagram, captioning the snap: "He gave me his heart on Valentine's Day, and I said YES!"

The 28-year-old and her beau first met in 2011 on the set of Gaga's music videobut they did not start dating until several months later.

Taylor and Gaga split briefly in 2012 but were soon back together again. Although they rarely make public appearances together, in a recent interview with radio DJ Howard Stern, Gaga couldn't stop gushing about how perfect she thought Taylor was.

"He is the right guy," she told Howard. "How do we know? It's this feeling..."

She also discussed what her wedding may be like, adding: "If I get married, I'll be hanging out in a pickup truck at a David's Bridal while my stylist is screaming at me."

In 2014 Taylor opened up on life with Gaga, telling: "I'm reserved, she's not. For whatever reason, it works. It works and that's that."

The actor admitted he was ready for children: "I do want to give mom grandchildren, of course. I think I'd be a good dad, it would be a pleasure. I'd love it - and I'm in my 30s now."
