American singer/songwriter Lady Gaga and her longtime boyfriend Taylor Kinney are engaged to be married.

The 33-year-old Chicago Fire actor popped the question to the 28-year-old singer, whose real name is Stefani Joanne Angelina Germanotta, on Valentine's Day.

The Born This Way singer shared the news on her Instagram account, along with a photo of a heart-shaped diamond engagement ring.

"He gave me his heart on Valentine's Day, and I said YES!" she wrote.

Kinney shared a picture of Lady Gaga wrapping her arms around him, confirming their engagement.

"she said YES on Valentine's Day," he captioned the picture.

The Bad Romance singer and Kinney started dating after they met on the set of her 2011 music video You and I.

During an interview with Fashion magazine in 2013, Lady Gaga gushed about her man.

"It has been hard for me to find it but I have found love," she said. "When you meet someone that's not intimidated by the amazing people that are around you [or] by the love that you receive—that's love. Men weren't always happy for me. It was very challenging to watch a woman be so successful."
