Model Irina Lazareanu is sitting out this runway season and plans to serenade the fashion pack instead. At the Anne Valérie Hash show on Wednesday, Lazareanu said she was plotting a secret Paris Fashion Week gig with Sean Lennon, who is helping her put the finishing touches to her debut album, titled “Some Place Along the Way.” The model will soon head to Japan to check the first designs for her collection for department store Seibu, which are based on her trademark mix of masculine and feminine pieces. Lazareanu, who walked in Hash’s couture show in January, said she was in no hurry to get back on the catwalk. “I would rather be on this side of the fence for a little while. I like it over here,” she said.
