Selena Gomez: El Hormiguero Hottie

Pushing forth with her strenuous travel schedule, Selena Gomez showed off her inner-scientist in Madrid, Spain on Tuesday (April 13).

The "Wizards of Waverly Place" darling was busy promoting her new album "Kiss & Tell" by making a fun-filled appearance on the Spanish TV show "El Hormiguero".

The stop in Madrid follows time spent in London, England, as Selena performed a free outdoor gig at HMV on Oxford Street the previous day.

In related news, Selena recently shot down continuous rumors claiming she's back with Nick Jonas, saying, “Not true — I’m single very much single. I’m trying to tackle everything — which is good because I’m young and I really should kind of date myself for a while — I should probably focus on myself a little bit.”
