Jennifer Lawrence is reportedly "fangirling" over Justin Bieber during the Cannes Film Festival over the weekend in which occasion the "Hunger Games: Mockingjay" cast held a party in a private mansion.

The "X-Men: Days of Future Past" star Jennifer Lawrence was overheard saying upon arriving at the Vanity Fair and Armani party at Hotel du Cap in Antibes, France on May 17, that she wanted to meet Justin Bieber.

Jennifer Lawrence eventually got her request regarding Justin Bieber at Cannes where she did manage to meet the teen pop star but she turned down the request for a photo op with the Canadian singer.

"She declined to take a photo with the Bieber because she just wanted it to be 'normal' when meeting him," E! News reported.

The meeting was confirmed by Vanity Fair which stated in a report, "We can confirm that they did indeed exchange pleasantries and that the party was made all the better for it."

The "Hunger Games: Mockingjay Part 1" was not officially listed for this year's Cannes, however the film was heavily promoted at the event, The Wrap noted. And "on Saturday night they did it in the flesh, throwing a big bash and showing off some footage from the massive blockbuster-to-be."

The "Hunger Games: Mockingjay Part 1" cast moved the party to a private mansion in Antibes just half hour's drive away from Cannes, hitfix.com reported.

The website also noted the distance to the party also prohibited the "familiar B- and C- level stars" from gatecrashing the party although Kellan Lutz of "Twighlight" and Scott Speedman of "The Captive" made their way to the party.

This year's participation of "The Hunger Games" cast had better luck than last year when the Lionsgate studio, the production and cast of "Catching Fire" had to contend with rain when they had a party at a beach last year in Cannes.
