Rebel Wilson popped the question to her now-fiancée Ramona Agruma during a romantic trip to Disneyland and is thought to have splashed out on the diamond engagement ring.
The Pitch Perfect star took to Instagram to announce her engagement and share a picture of the enormous sparkler, which has been estimated to be worth a massive $150,000 (£125,000).
In the sweet post, the loved-up couple posed in matching pink and white striped jumpers with navy blue hearts on as they showed off the ring adorning Ramona's finger.
Rebel revealed that the ring is from Tiffany and Co., with a jewellery expert estimating that the 2.55 carat ring comes with a hefty price tag.
Maxwell Stone, leading diamond expert from Steven Stone said: "A huge congratulations are in order for Rebel Wilson and Ramona Agruma - and what a magical location Disneyland is for a proposal.
"Ramona's sparkler is the Tiffany Setting Engagement Ring - a true masterpiece, the design is the world's most iconic engagement ring.
"The ring features a 2.55 carat round brilliant cut diamond, in a six prong setting. Flawlessly engineered, the six-prong setting virtually disappears and allows the diamond to float above the platinum band."
He added: "It's particularly heartwarming to see that Rebel chose a ring from Tiffany's as a friend gifted the couple Tiffany heart charms on their first-ever date in Los Angeles in late 2021.
"I'd estimate Ramona's ring to be worth $150,000."
After Rebel shared the happy engagement news on Instagram, her famous friends rushed to offer their congratulations.
Paris Hilton commented: "Love you girls! So happy for you two! Such a magical way to get engaged. Congrats!"
Rebel's Pitch Perfect co-star Brittany Snow wrote: "Rebs!!!! Magical congrats you two!!"
Octavia Spencer said: "Congratulations sweetie!!" while Chrissie Fit added: "Rebel and Ramona forever. Love you babes so much!"
Rebel announced she was dating Ramona in June 2022 taking to Instagram to share the news as well as confirm her sexuality.
At the time she wrote: "I thought I was searching for a Disney Prince… but maybe what I really needed all this time was a Disney Princess."
