Britney Spears has posted a photo on Twitter, teasing fans awaiting her new track with Iggy Azalea ‘Pretty Girls.’

The singer posted a photo that appeared to be taken on the set for the ‘Pretty Girls’ music video alongside lyrics from the track.

‘Pretty Girls’ is due to be released on May 5 in the US, a UK release date is yet to be set. Spears teased lyrics from the track with help from a string of emojis.

On Wednesday (April 8) Spears posted a photo of dancers in a studio with the caption, “Aren’t these girls pretty?”

As reported, the new single ‘Pretty Girls’ sees Britney Spears team up with Iggy Azalea and Little Mix.

The track is to be produced by The Invisible Men, who helmed the Azalea hit ‘Fancy’, while girl band Little Mix are listed as co-writers.

Spears has played a residency at Planet Hollywood in Las Vegas since 2013, the year her most recent album ‘Britney Jean’ was released. Speaking to Billboard last week, the singer claimed she is working on a new album, but is concentrating more on raising her sons, nine-year-old Sean and eight-year-old Jayden, with her ex-husband Kevin Federline.

“I’m going to do a new album slowly but surely,” said Spears. “There’s a lot going on with my kids and schools. I’m going to do my best to make an amazing new album, but it’s not my full priority right now.”

Spears also recently revealed she has been taking maths lessons.

The singer said she is taking classes so that she can help her two sons with their homework.

She told People magazine: “They go to a really hard school, and this week we had three hours of homework [a night].

“Some of it is hard for me,” she added. “Next year when [Sean Preston’s] in fifth grade, he’s going to be doing pre-algebra, and I’m taking classes so I know how to do it.”
