Alex & Sierra shot to superstardom when they were crowned the season 3 winners of The X-Factor USA. The twosome proved they had staying-power when they released their debut album, It’s About Us, last fall.
The pop duo's current single, "Little Do You Know," is a heartbreaking tune penned by 24-year-old Sierra and her girlfriends – and only the second song she ever wrote. The inspiration? Her relationship with 23-year-old Alex.
“That one was kind of a magical song… I think we wrote it in less than an hour,” she shared. “It was personal, I think that made it easier to write…. Not all of our songs are exactly stuff that’s happened with us, but that one, yeah.”
One song on the album not penned by Alex & Sierra? The sweet tune called “I Love You,” that is credited to writers Johan Carlsson and Mick Greenberg (who many One Direction fans believe is Harry Styles’ writing alias), about a guy who falls in love with a girl but never expresses to her how he feels – making her think he doesn't care.
So who exactly is Mick Greenberg? The pair starts laughing when asked that question.
“We were told that Mick Greenberg wrote it. That’s what we were told, that’s all we know,” Alex playfully explains as Sierra continues laughing. “It could be Shaq! We don’t know… Shaquille O’Neil might have written it.”
The song boasts several lines that 1D fans think reference Taylor Swift lyrics. An example? One line says “While we laid there on the soft warm ground for a week and thirteen days” – a suspicious parallel to a line in Taylor’s “I Knew You Were Trouble” that reads “Now I’m lying on the cold, hard ground.” It’s also famously known that Taylor’s favorite number is 13. Another line in the song that might be a giveaway? “I won't trouble you no more.”
Alex & Sierra gave one more subtle hint that Mick is indeed Harry, adding, “Maybe Mick and Taylor are really good friends… Maybe Mick & Taylor had a fling!"
In any case, the tune most likely won’t be Alex & Sierra’s next single. If it’s up to them, it’ll be “Give Me Something.”
“I think that’d be a cool single and we have a lot of fun doing it,” Alex says.
This past year has been a whirlwind filled with memorable moments galore for the pair. For Alex, playing Radio City Music Hall and spending a weekend working with Jason Mraz are among his favorites. For Sierra, it's all about the interaction with their fans at shows.
"In general, it happens every show whenever we see someone singing our lyrics," she explains. "That's crazy because I've always been the one singing other people's lyrics!"
