Taylor Swift's Red Tour just wrapped in the U.S. after an incredibly successful run. Now, the singer is taking the trek overseas to London. Due to the overwhelming response to and speedy sellouts of the first three dates at the O2 Arena, Swift has added a fourth date at the venue.

It's simple economics and the law of supply and demand. London fans want more Taylor Swift, and they're getting her.

The fourth Red Tour concert is set for Feb. 10, following scheduled shows on Feb. 1, Feb. 2 and Feb. 4. So Swift will enjoy a four show stint across the pond, just like she did in L.A. earlier this summer. The singer performed four shows at the Staples Center, setting a ticket sales record in the process.

Swift's team posted the good news about the new date on Facebook. Her note read as follows: "Wow! Due to amazing demand, Taylor has added a fourth show at the O2 Arena in London, on Feburary 10th, 2014! Tickets are on sale NOW."

And the Red Tour keeps on trucking as a now-global phenomena. We're left to wonder which English pop stars and artists will be invited to perform onstage with her. Stay tuned.
