"Last month I was with my best friend Taylor Swift she's one of the most incredible sweet people ever," she gushed. "We were in the car…and my song came on and we freaked out, and then her song came on and we freaked out."
"People probably think we're so lame, but we get so excited to hear our songs on the radio," Selena added.
When asked how the two pop stars have maintained their friendship, despite nonstop tour schedules and press commitments, Selena explained that keeping things as normal as possible is the key.
"We don't roll with an entourage," she told the hosts of the show. "If we want to go to the movies or go shopping, we do that."
But downtime with her lady friends may have to take a backseat for a little while, as Selena has just hit the road for the start of her Stars Dance tour.
She hit the stage in Vancouver Wednesday night in a slew of figure-hugging costumes.
The 21-year-old also joined in on Hollywood's biggest trend this year: crop tops. She donned two midriff-bearing looks including a skimpy bra top with white harem pants.
Baggy bottoms aside, most of the costumes also featured detachable floor length skirts, which the singer ditched to reveal her more provocative bodysuits.
After debuting her latest looks the brunette beauty tweeted her appreciation: "Vancouver!! We had FUN! Can't thank y'all enough for an AMAZING 1st show!"
