After four years of dating, and one break up last summer, the couple is finally getting engaged. Nick, who’s best known for his public relationship with Jessica Simpson, started dating Vanessa in 2006. As for the engagement ring? According to Us Weekly, Nick proposed with a platinum, asscher cut diamond with trapezoids on the side from Bader & Garrin. There are no pictures of the ring yet, but, going on just the description alone, we’re betting the ring looks similar to this asscher cut ring by Natalie K.
