Looks like they’ve already met the parents.
At Friday’s Race to Erase MS gala at the Hyatt Regency Century Plaza Hotel in L.A., they shared a table with family, including Jenner’s mom, Linda Thompson, whom Lavigne greeted with a long hug. Then, the two spent the rest of their night looking very smitten with each other and sharing some PDA at the table.
The singer, who performed five of her hits at the event, later took to Twitter, where she and Jenner continued their lovefest, completing each other’s sentences and getting lovey-dovey back and forth.
The two have become fixtures at Voyeur, a West Hollywood lounge, where they’ve partied on consecutive Thursday nights. During a recent visit, the two shared kisses in their banquette and “acted like they were the only two in the club,” an onlooker said.
