“[It’s] probably about 80% of the way done. I’m thrilled with it. I spoke to her this morning and she said ‘This is my favourite album that I’ve ever done’,” Rudolph told the Las Vegas Sun.
“It’s different, it’s a turn. The last few albums have been pretty straightforward pop. This is almost like if you can imagine Britney meets The Weeknd. It’s got a really interesting vibe, it’s a lot of really cool stuff.”
Rudolph confirmed that there was no working title yet, but the record is likely to be released later this year.
He continued: “I think people are going to absolutely love it. She sounds amazing on it. She has not sounded better in I don’t know when.
“She’s really excited about it, she’s done a lot of writing on the album and I think it’s gonna be really big.”
Spears’ last album was 2013’s ‘Britney Jean’, which peaked at number four in the US and 34 in the UK.
The singer recently posted a video of herself dancing to Adele’s ‘Hello’, along with the message, “I could dance to this song a MILLION times… Love you Adele!”
She joins the list of famous names sharing tributes to the song since its release over a month ago, which now includes Rick Ross, James Corden, Ellen Degeneres, The Maccabees, Demi Lovato and Lionel Richie, the latter of whom engaged with a meme that emerged after ‘Hello’’s debut.
