Billie Lourd is back together with ex-boyfriend Austen Rydell. The couple was seen engaging in PDA at the Moët Moment Film Festival on Friday. The two were spotted kissing inside the venue, and an eyewitness told Us Weekly that the actress and Rydell tried very hard to be discrete. Lourd was previously linked to 'Twilight' star Taylor Lautner but the pair split in July 2017 after several months of dating.
