There's a legit reason as to why Nicole Kidman was clapping so strangely when cameras panned to her at the 89th Academy Awards last month.
During an interview on Australia's Kyle and Jackie O radio show on Thursday morning, the Lion star revealed that it was her 119 carats of Harry Winston jewels, which included a pear-shaped ring, that were responsible for her bizarre round of applause.
“It was really awkward," she admitted of her clapping. "I was like, 'I wanna clap, I don’t wanna not be clapping.' That’d be worse, right? Like, 'Why isn’t Nicole clapping?'"

Kidman further explained, "So therefore I’m clapping but it was really difficult because I had a huge ring on that was not mine -- but it was absolutely gorgeous -- and I was terrified of damaging it."
The 49-year-old actress also recalled another uncomfortable moment at the Oscars when La La Land was declared the winner of Best Picture when the award was really meant for Moonlight. "It was bizarre. I wasn’t sure what was going on. No one in the audience was," she shared. "Then there was some shuffling, envelopes -- and people rushing onstage. I was like, 'What is going on?'"

Kidman said at the time, she feared it was some kind of medical emergency. "I thought someone wasn’t well," she explained. "And then I saw people’s faces dropping. It was bizarre."
Now that award season is over for the most part, Kidman can focus on another big event coming up in June: her 50th birthday. "I'm planning stuff right now that I can't talk about!" Kidman's husband, Keith Urban, dished to ET. "I feel incredibly lucky and blessed, definitely."
