You'll learn about not just the details of the carat size and ring value, but a few insiders into the relationships between the stars as well.

Jennifer Lopez

Occasion: J.Lo and Ben Affleck's second engagement // Value of Ring: Estimated value of up to $10 million J.Lo and Ben Affleck, known as Bennifer, showed the world that second chances really do happen. Bennifer's romance first started in December of 2001 and Ben proposed a year later with a 6.1-carat pink, solitaire ring! However, just days before their wedding, the couple called it quits.

Fast forward to 2021, Bennifer rekindled their relationship. In April 2022, Ben proposed with a rare 8.5-carat, green diamond ring. The couple tied the knot in Vegas and later had another wedding, celebrated with friends and family at Ben's Georgia home.

Blake Lively

Occasion: Blake Lively and Ryan Reynold's engagement // Value of Ring: $2 million Blake and Ryan are undoubtedly one of Hollywood's greatest power couples. Despite first meeting in 2010, the pair went on a double date a year later. However, they were on this double date with different partners... awkward. In 2012, Reynolds proposed with a 12-carat diamond. The ring is valued at $2 million.

Their wedding was described as picture-perfect, however, a sparkler burnt a hole in Blake's gown. Reynolds turned the heartbreaking incident into an endearing memory which has now become Blake's favorite part of her dress. The couple has three daughters, and they recently announced that they're expecting their fourth child.

Heidi Klum

Occasion: Heidi Klum and Seal's engagement // Value of Ring: $150,000 Heidi met Seal in the lobby of a hotel in 2004. Seal wasted no time and proposed with a 10-carat, canary diamond ring. Seal planned an elaborate proposal where he took Klum to the Canadian Rockies. As expected, there were rose petals laid out to set the mood... inside of an igloo.

The couple married in Mexico, and they have three children together, with Seal even adopting Klum's first child from a previous relationship. Every year, the couple renewed their vows as a romantic tradition. Unfortunately, though, the model and singer separated in 2012 before officially divorcing in 2014. The two remain close friends, however, and continue to co-parent their children together.

Serena Williams

Occasion: Serena Willams and Alexis Ohanian's engagement // Value of Ring: $2 million Serena met Alexis by chance in 2015 while having breakfast in Rome. Alexis attended the Italian Open the day he met Serena and she invited him to the upcoming French Open. He flew to Paris for the weekend to watch her play and the rest is history.

In 2016, Alexis proposed at the very hotel they first met in. He popped the question with a 12-carat emerald-cut diamond ring. A month after the proposal, the couple found out that they were expecting. With three outfit changes and a star-studded guest list, Williams and Ohanian tied the knot in 2017 - and it was apparently the wedding of the year.
