The 'Make Me' hitmaker only released her ninth studio LP 'Glory' in August and has already been recording some new tunes for her follow-up, although she's not sure what the overall style will be.

She mused: "I'm not sure what I want the next album to sound like.

"I just know that I'm excited to get into he studio again and actually have already been back recording."

The 34-year-old pop superstar was really pleased with how well 'Glory' turned out and how experimental and different it was from her previous outings and has hinted she could change it up once again on the next record.

In an interview with the blog Vegas Player, she said: "I think the vibe of 'Glory' is a lot different to my previously albums.

"We experimented with so many things while we were making the record.

"I feel like this time, I was really able to be hands on.

"I'm so proud of every song that we put on the album ... the songs on 'Glory' were no-brainers for me - they were the best of all the songs we recorded."

Britney's latest single from the album is 'Slumber Party', which comes with a sexy music video featuring Tinashe.

The 23-year-old singer joins the 'Work Bitch' hitmaker at a sleepover, in which they writhed around on top of a group of half-naked dancers whilst they sang, "we ain't gonna sleep tonight" in the steamy clip.

Britney makes her way into the house, it is clear the party is in full swing and she surveys the guests that have gathered at the property.

By the second verse, Tinashe appears in a cleavage-baring blue corset, where she sings, "Let's fill up this clawfoot bath with bubbles / Loving me so hard it's causing trouble / If it's seven minutes in heaven, make it double." Soon, she is joined by Britney and they share an intimate moment.

Later in the video, Britney sets pulses racing as she seductively crawls down a table and laps up a glass of spilt milk.
