The 'Bad Romance' hitmaker told fans in the audience at her 'Cheek to Cheek' concert with Tony Bennett: "I'm getting a little older and many people think I'm pregnant but I tell them, 'I'm just almost f**king 30.'"
Gaga, 29, didn't only talk pregnancy with fans, but she also gushed about Chicago Fire actor Taylor.
"I just tried to skype with my fiancé. He's in Serbia," she said later that evening. "Every little bit I get with him, it's not a lot, means so much."
On Valentine's Day (14 February), Taylor popped the question to Gaga.
Gaga revealed how she was "crying" tears of happiness after Taylor proposed to her with a candy ring - but he later presented her with the real diamond!
Gaga - real name Stefani Joanne Angelina Germanotta - met Taylor four years ago while filming her 'You and I' music video.
Following their engagement, Gaga revealed that her ring had their initials on the underside of the band in diamonds.
She also gushed: "I'm such a happy bride-to-be! I can't stop smiling!!"
