Jacob Elordi and Olivia Jade Giannulli are over for good after their briefly rekindled relationship. "It was very short-lived, and they were seeing each other for about a month before they figured out it wasn't working again," a source exclusively tells Us Weekly. "Olivia has been in NYC and Jacob has been filming, and has his home base in L.A., so distance was a factor." The insider adds that the relationship "ran its course," and Elordi, 28, and Giannulli, 26, "realized they are better off not together." "Jacob is already seeing someone else and has been on dates," the source concludes.
