The "Toxic" hitmaker recently shared a throwback photo of herself and the "Revenant" actor and it was a ploy by the 34-year-old singer to strike up a romance with the 41-year-old star, reported Femalefirst.
"Britney has insisted she'll do whatever it takes to catch Leo's attention and has even sent him tickets to her Vegas show, as well as reaching out to him personally on Twitter after taking control of her social media accounts again," a source said.
