Everybody’s favorite music wild child, Britney Spears, once sang “I’m addicted to you, don’t you know that you’re toxic,” but she took a more low-key approach to her second failed relationship with her manager, Jason Trawick. Trawick proposed to Spears in 2011 at his 40th birthday dinner in Los Angeles. Spears tweeted that she “can’t wait to show” everyone her ring, and she revealed the 3.5-carat diamond ring at Trawick’s birthday party in Las Vegas. Jeweler Neil Lane, the designer, said the ring is a white diamond in a handmade platinum setting that “looks like a mini crown” with 90 small round diamonds on the eternity band. “Jason didn’t want some over-the-top stone,” Lane said. Fitting, perhaps, of how much more low-key this relationship was than her first marriage with ex-husband Kevin Federline, who proposed with a five-carat diamond ring in 2004.
