While the two were not spotted kissing, an employee at the restaurant confirmed that they arrived together. Their lunch date comes amid reports that the two have begun seeing other once again.
Jenner and Styles were spotted at another dinner date on Thursday at Ysabel in L.A., and the 20-year-old model was all smiles during the meal, People reports. A source told the publication that the two are "are trying to spend time together again," and "rekindling their old romance."
The two were first romantically linked in November 2013, but never confirmed their relationship. After some time apart, the couple were spotting getting very cozy on a yacht in St. Barts in December 2015.
