She hadn't been spotted out with model boyfriend of four years Oliver Cheshire - prompting speculation the young couple had split.
But performing a series of gigs in London to celebrate Pizza Express' 50th birthday last weekend, Pixie Lott told Closer the pair were still an item.
She said: "Ollie has been in New York for Fashion Week. He wasn’t on the catwalk over there but he was writing a fashion blog. He actually writes a lot of fashioned based stuff for magazines now. I really missed him but he’s here tonight to watch me perform."
She adds: "Oliie will come whenever he can to what I am doing. He knows how much my career means to me and it’s going to be hard to be apart as I’m now going to be spending time in America working on my album. But we'll make as much time for each other as we can."
