Instead, she stuck around to enjoy London—and she's not enjoying it alone!
The 23-year-old pop star was spotted tonight leaving a pub and heading out to the members-only Groucho Club with 22-year-old British singer-songwriter Tom Odell, who scored the Brit Award for Critics' Choice last night.
With her most recent ex, Harry Styles, in attendance, Swift turned in a fierce performance of "I Knew You Were Trouble," stripping off an old-fashioned white wedding dress she came out with to reveal skin-tight black hot pants and a lacy halter top.
Despite losing out to Lana Del Rey for Best International Female Solo Artist, she then danced the night away at the Bacardi-hosted afterparty with Frank Ocean, Carey Mulligan, Marcus Mumford and Ellie Goulding.
Odell, who was spotted getting flirty with Swift backstage at the Brits, released his debut EP, Songs From Another Love (sounds like he and Swift may have a few things in common), last October and his first studio album, Long Way Down, is due out April 15.
