Christina Aguilera played her new single “Keeps Getting Better” at the 2008 MTV VMAs on Sunday night. The singer looked amazing in a black cat suit with a black eye mask. With a futuristic sound, “Keeps Getting Better” belongs to Christina’s upcoming greatest hits set. Before the event started, she told reporters, “I'm very excited to be coming back with my new stuff. This will be his [Max's] first time watching me perform on television, but only for a little while because he's not really allowed to watch television yet."
