During her travels, the star was spotted sans ring while partying with a group of ladies and her mom, Cynthia Germanotta, at Mandala nightclub. Another eyewitness saw Gaga lounging at the Resort at Pedregal, wearing a pink American Apparel swimsuit, Perverse sunglasses and Karissa sandals from Frye.
She also visited the boys at the Casa Hogar de Cabo San Lucas A.C orphanage. “[Gaga] was very humble, kind and down to earth," Omar Venegas, the orphanage's operations manager, tells ET. "She was here with her mother. They both were taken with the boys and told us they want to help us develop our new girls facility that we are in the process of raising funds for."
Gaga also took selfies with the boys and sang with the boys. She also brought dinner to them all from the luxury hotel she was staying at in Mexico.
One of the last times Gaga was spotted with her ring was at the Indy 500 on May 29. While she also had a ring on that finger during her visit with the Dalai Lama last month, it didn't appear to be her engagement ring.
The 35-year-old actor started dating the singer five years ago after they met on the set of her music video, "You and I." They got engaged on Valentine's Day last year.
"It was so special," Gaga told ET a few weeks after the proposal. "It was actually funny, he first gave me a Ring Pop – a candy Ring Pop – and I was crying so hard, and I said yes right away, and then he pulled out the heart-shaped diamond and I said, 'Oh, God!'"
Last October, the Chicago Fire star also shared with ET how he saw their nuptials playing out. "I told her I don't mind doing the little white chapel thing," he said. "She wants what she wants. I want to make sure that it's right what she wants."
