International pop star [artist id="500933"]Robyn[/artist] blends her futuristic sound with the sunny pop of her homeland, Sweden. This past Halloween, she [article id="1673593"]headlined MTV's O Music Awards[/article], and no one was left dancing alone during her showstopping set. The "Call Your Girlfriend" singer said performing at the awards show "was not like doing a TV show -- it was a concert."

Robyn wasn't always landing gigs that big, but she has been singing girl-power anthems like "Show Me Love" and "Do You Know (What It Takes)" since she was just a teenager. She reminisces about that time in her life on the next episode of "When I Was 17," airing Saturday at 11 a.m. ET/PT on MTV.

"When I was 16, I recorded my first album and it was released in Sweden and it did really well," she says on the episode, also featuring J. Cole and Chad Michael Murray. "So labels in America started to pay interest to what I was doing, and when I was 17, I signed a record contract in America."

Just like ABBA years before her, America kept this spunky Swedish girl busy -- in more ways than one. "I spent all my time in hotels," she said. "I was constantly working and moving around. But I stayed a lot at this one hotel in New York, where I had a romance with the bellboy."

So what was her bellhop beau like? "He was my age, and his name was Alex. He was amazing. If anyone at the hotel would have found out that we had a thing going on, I don't think Alex would have been able to keep his job. There was a lot of sneaking around in the corridors."

"When I Was 17" -- this week featuring Robyn, J. Cole and Chad Michael Murray -- airs Saturday at 11 a.m ET/PT on MTV.
