Lady Gaga reveals Taylor Kinney proposal prank

Lady Gaga may have gushed about her super-sized diamond engagement ring on social media, but she would have been just as happy with a Ring Pop!

Mother Monster stopped for a chat with ET on the Oscars red carpet Sunday, where she revealed details about Taylor Kinney's romantic Valentine's Day proposal.

"It was so special," she gushed. "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!'"

(For those wondering, the Ring Pop in question was Blue Raspberry flavored.)

Gaga shared this photo of her stunning Lorraine Schwartz engagement ring, estimated to be worth between $400,000 and $500,000, on Instagram, shortly after the proposal.

The 28-year-old singer said that she has not yet started planning the nuptials, but that pal Tony Bennett could play a role in the couple's big day.

Gaga was on hand Sunday for a special tribute performance during the Academy Awards ceremony.

"I really put my heart into this performance," she said. "It's a tribute performance for a remarkable film that changed the history of cinema forever and I'm just very honored to be doing it."

The bride-to-be hit the red carpet in a stunning white gown, paired with red gloves, by Azzedine Alaia.

"He's one of the greatest designers in history," she said. "He's never ever made a custom piece for the Oscars before, so I'm very honored to be wearing this tonight."
