Jennifer Lopez and Taylor Swift are to collaborate on a new track.

The 44-year-old singer and the 'Everything Has Changed' hitmaker have reportedly locked down a plan to duet on Jennifer's upcoming eighth studio album - expected later this year - after they performed together during Taylor's final 'Red Tour' show last month.

A source told ''Both of them are huge fans of each other and excited to work together!''

The blonde beauty recently shared behind-the-scenes footage from her gig at the Staples Center in Los Angeles, which shows Jennifer saying: ''Thank you so much for allowing our family to come and be a part of your family.

''To create a beautiful moment, thank you, Taylor, for being so gracious and beautiful and loving me enough to have me be here tonight. I feel very blessed to be able to share the stage with you, and I just hope that everybody has the best show that they could ever have.''

Meanwhile, the 'American Idol' judge has recruited singer-songwriter Sia for one of the tracks on her collection and is said to be joining forces with Chris Brown for another song.

Sia tweeted previously: ''Worked with jenny from the block yesterday. (@JLo !) what a charming, sweet, funny person. And she can really SING! Anyhoo. Super fun. (sic).''
