Are Olympic athletes Evan Lysacek and Nastia Liukin back together? The world champion ice skater and gold medalist in gymnastics were spotted together on an intimate dinner date in London during last week’s games. The two reportedly dated back in 2010, and Lysacek interviewed Liukin this week for a segment on NBC.com. But we’re also told the former couple just had dinner alone at sushi restaurant Roka at London’s secluded Canary Wharf. “They were very flirty and left together holding hands,” said our source. A rep for Lysacek had no comment, and Liukin’s rep didn’t get back to us. On Friday, Lysacek announced his return to competitive ice skating after winning a gold medal in the 2010 Vancouver games. Liukin won gold in the women’s all-around competition at the 2008 Beijing games, but she failed to qualify for this year’s Olympics. She’s now reportedly attending NYU, and she’ll perform here in November as part of the Kellogg Tour of Gymnastics Champions.
