"It's a mixture of pop/rock and what I do," the "Love the Way You Lie" hitmaker told Rap-Up TV. "We've got some things that are hip-hop leaning, and we've got some things that are more pop/rock leaning, so it's what we both do just kind of combined into one thing."
The British producer explained that the songstress had her label reach out to him after hearing B.o.B and Hayley Williams' mega-hit "Airplanes."
As hinted in the letter Lavigne posted on her website to her fans this past week, Alex suggested that the singer has experienced some hardships with her record label when it comes to the release of the yet-to-be-titled album.
"I'm not sure what's going on with the album, just because she's been working on this album for a long time," he said. "So I think there's a lot of stuff going on politically and behind the scenes.
"I really liked working with her," he added. "She's really cool and down to earth. It was a good experience."
He recalled their drunk studio sessions, but kept tight-lipped about other track details, saying, "We're working it all out, so it's probably too early to talk about it."
While he might not know exactly when the LP will drop, Alex knows all too well about fans' pleas for new Avril Lavigne material.
"Her fans hit me up on Twitter every day about 'When's the album coming out?' 'When's the single coming out?' so I know there's a big demand for it," he said. "Hopefully, it'll be out soon, and we'll see what happens."
