Megan Fox's 18ct White Gold Engagement Rings from MGK Are Not Her First — She Once Lost Her Ex's 2ct Ring

Megan Fox and Machine Gun Kelly are officially engaged after just over a year of dating. Fox's ex-husband, Brian Austin Green, has already commented on the news.

"Jennifer's Body" star Megan Fox is happily engaged to rapper Machine Gun Kelly. However, before the pair were an item, Fox was married to "Beverly Hills, 90210" star Brian Austin Green.

The former couple met while filming "Hope & Faith" when Fox was 18. At first, Green was hesitant to enter a relationship with her due to their age gap, but Fox pursued him, and they became a couple.

Green first proposed to the "Transformers" actress in 2006. However, three years later, Fox and Green quietly called off the engagement amidst rumors Fox was having an affair with her costar Shia LeBeouf.

A few months later, Fox said "Yes" when Green popped the question again on a beach in Hawai'i. However, Fox was so excited she ended up dropping the 2-carat diamond engagement ring into the sand.

Hotel staff spent hours combing through the sand to find the ring, but unfortunately, the search was unsuccessful. Despite the lost ring, the couple married the same year.

Two years later, Fox and Green welcomed their first son, Noah Shannon. Then in 2014, their family grew with the birth of the son, Bodhi Ransom, and later they welcomed their youngest child, Journey River, in 2016.

After ten years together, the couple decided to file for divorce and share joint custody of their three children. Each parent has moved on to new relationships and seems very happy.

Fox and her "Blood Valentine" artist revealed their engagement this month. Kelly popped the question with a gorgeous and sentimental engagement ring designed by celebrity jeweler designer Stephen Webster.

The ring consists of two pear-cut gems, an emerald (Fox's birthstone) and a diamond (Kelly's birthstone.) The stones are set on "two magnetic bands of thorns," two 18 carat white gold diamond pavé bands.

Kelly proposed with the jewelry piece that symbolizes their love after dating Fox for just over a year. The newly-engaged couple met while filming her movie "Midnight in the Switchgrass."

A source revealed Green has no bad blood towards his ex-wife and "as long as they're both on the same page with the kids, he's good and happy for her." Green has moved on too and is currently dating the "Dancing with the Stars" dancer Sharna Burgess.
