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.

"Both of them are huge fans of each other and excited to work together!" a source said.

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)."
