Lindsay Lohan isn’t a fan of Hollywood's sweetheart, actress Jennifer Lawrence, and now we know why!

Following Lohan’s dig at Lawrence in which she allegedly said that the actress “sleeps around” to win film roles, Radar Online published a report via Star Magazine Wednesday claiming that Lawrence’s boyfriend, British actor Nicholas Hoult, once turned down the “Parent Trap” star. “She tried to hook up with him in 2010, but he wouldn’t give her the time of day,” said a source.

According to an insider, Lohan, 27, was persistent in trying to win over the now 24-year-old “X-Men” film star. “She called him nonstop,” said a source, adding that Lawrence’s beau of three years eventually turned down the film star. “Finally, he told her to buzz off,” said a source.

According to the report, Lohan, most recently of “Lindsay” docu-series fame, is now taking her frustrations with Hoult out on the 23-year-old “Hunger Games” star. “Now she’s bitter and taking out her anger on Jen,” said a source.

Lohan last made headlines in April for accusing Lawrence of using her sexuality to secure multiple film roles in an (allegedly fabricated) interview with Kode Magazine. "She’s so fake," Lohan reportedly said when speaking of the Oscar winner, going on say, “I’m sorry. I’m not going to f—k for roles.”

Prior to her Kode Magazine dig, Lohan bashed Lawrence following her 2013 Golden Globes win after the actress beat out fellow contender Meryl Streep and made a “First Wives Club” movie reference during her acceptance speech. “Words cannot express how much I LOVE Kristen Wigg. And no 1 should ever mess with a legend, such as Meryl Streep,” Lohan shared on Twitter.  

Lawrence and Hoult first became an item in December 2010 after filming the sci-fi feature “X-Men: First Class.” The pair, who split in February 2013 due to conflicting filming schedules, rekindled their relationship prior to filming the “X-Men” sequel, “Days of Future Past," last April.
