Congratulations, Sofia Richie! The model just announced her engagement to partner Elliot Grainge on Instagram." Forever isn't long enough @elliot." with the caption.

Sofia, daughter of Lionel Richie and sister of Nicole Richie, posted a perfectly stunning shot of Grainge on one knee and her hand over her mouth, just like her previous engagement photos. In the photo, the lovebirds are surrounded by candles against a background of palm trees.

In the second photo, the celeb and her new fiancé are kissing. Her hand is above his face, giving him an easy view of her huge ring.

"Sofia's ring appears to be set in platinum, giving her peace of mind that her stunning diamond is safe," Jenny Luker, president of the Platinum Guild International USA, told Marie Claire. [The thin platinum band is set with an emerald-cut center diamond of approximately 6 carats. The diamond is set in platinum, a naturally white metal, which makes it even more brilliant! This ring would cost $300,000.

"Emerald-cut diamonds set in platinum are a popular style because they are both modern and classic. Celebrities such as Beyonce, Reese Witherspoon, and Karlie Kloss have similarly styled engagement rings.

Sofia, 23, first made headlines when she dated Justin Bieber in 2016. Her subsequent relationship with Scott Disick raised eyebrows (including Lionel's) for over three years until she broke up with him in 2020.

Grainge was a music executive with whom Sofia began dating in 2021. At the time, a source told Us Weekly, "They started as friends before becoming a couple, and now it's getting serious; their relationship is on track, getting closer and closer, and they spend practically every day together."

Celebrities such as Jasmine Tookes, Chiara Ferrani, Ashley Tisdale, Paris Hilton, Bella Hadid, and Miranda Kerr have all offered their congratulations.
