India, Sept. 13 -- Actor Nina Dobrev (36) and Olympic snowboarder Shaun White (39) seem to have ended their six-year-long relationship. The couple, who went public on Instagram in May 2020, had been engaged for nearly a year. A source close to the duo told PEOPLE, "It was a mutual decision, and wasn't an easy one, but it was made with love and deep respect for one another." While neither has officially confirmed the breakup, Nina posted a Reel shortly after the news broke. In the video titled "For women trying to fix their man", she lip-synced the line: "Listen, Bob the Builder, he's got 10 other women trying to fix him too, and you all look like a damn construction crew." The post quickly led fans to speculate that it was aimed at her ex-fiance. The couple was last seen together on August 31, but Nina appeared at the Toronto International Film Festival on September 7 without her ring, sparking breakup rumours. HTC...
