Nina Dobrev walked the red carpet at the Toronto International Film Festival without her engagement ring, an absence that came four days before news that she and Shaun White had ended their engagement.

The "Vampire Diaries" alum, 36, attended the premiere of Eternity at Roy Thomson Hall on Sunday in a black silk gown and silver stilettos. Her five-carat Lorraine Schwartz diamond was notably missing from her left hand during photos and interviews, a departure from earlier appearances this week in which she displayed the ring.

People reported Thursday that Dobrev and the three-time Olympic gold medalist, 39, had ended their engagement after five years together. An insider told People the decision "was a mutual decision, and wasn't an easy one, but it was made with love and a deep respect for one another." The outlet did not specify reasons for the split.

The pair were last photographed together running errands in Los Angeles on Aug. 31, and Dobrev had posted a carousel of photos earlier in the week showing her wearing the engagement ring. Page Six reached out to representatives for comment and did not immediately receive responses.

Dobrev and White went public with their relationship in May 2020 and confirmed their engagement last October. Dobrev shared images of the proposal on Instagram at the time, captioning a series of photos "RIP boyfriend, hello fiancé 💍♾️." In interviews, Dobrev described the proposal as a surprise; she told Vogue she "went into shock" and "just froze and stared at him." Friends later joined the couple to celebrate the engagement.

The missing ring drew attention given the timing: Dobrev's TIFF appearance occurred over the weekend, and the People report about the split followed on Thursday. Media outlets have noted the contrast between recent public outings in which Dobrev displayed the ring and her latest red-carpet appearance without it.

Neither Dobrev nor White has issued a public statement beyond the People report citing a source close to the couple. The two have maintained relatively private profiles around their relationship in recent years, although both have shared select moments with fans on social media and in interviews.

The development is the latest in a series of high-profile Hollywood splits this year. Details about any future public appearances or professional plans related to the couple were not immediately available.
