Lady Gaga "cannot stop smiling" following her engagement to Taylor Kinney.
The 28-year-old star took to her Instagram account to post another picture of her incredible heart-shaped ring after her fiance popped the question on Valentine's Day (14.02.15), and revealed he has always called her by her birth name, Stefani, since their first date.
She captioned the image: "My favorite part of my engagement ring, Taylor and Lorraine designed "TS" in white diamonds on the band. He always called me by my birth name. Since our very first date. I'm such a happy bride-to-be! I can't stop smiling!! (sic)"
The star later continued to celebrate her engagement by enjoying a spot of swimming pool yoga in the scorching sun.
She captioned a picture: "What a wonderful day, Swimming Pool Yoga! (sic)"
Gaga - who started dating the 33-year-old actor in 2011 - confirmed her engagement on Monday night by sharing a picture of her band on her Instagram account.
She wrote: "He gave me his heart on Valentine's Day, and I said YES! (sic)"
The couple celebrated their happy news at her parents' restaurant, Joanne Trattoria, in New York, where the star was said to be "glowing".
An eyewitness said: "Suddenly, she puts out her hand and starts showing off her ring, just the way any newly engaged woman would. She wasn't loud, but she was very excited. I would say she was glowing."
