Noah Centineo and his girlfriend Alexis Ren are now red carpet official. The couple made their red carpet debut on Saturday night at the UNICEF’s Masquerade Ball.

The couple were rumored to be dating last month when he was seen picking up Ren from the airport.

“He picked her up as she was on my flight. He was waiting for her at baggage claim,” a source told Us Weekly. “He kissed her on the head, [and] they were holding hands and hugging.”

Earlier in September the two were spotted out at dinner together with a group of friends where they were acting rather coupley.

“He was with a group of five people: two girls and two guys, plus him,” another source said. “As he walked away, he wrapped his arm around [Ren] and kissed the side of her forehead and kept her in a tight side-hug as they walked to the valet. It looked pretty lovey to me.”

Ren previously dated her Dancing With the Stars partner, Alan Bersten, but the couple broke up back in December due to their busy schedules.

“She’s in Japan working and he’s going on tour in a couple of weeks, but they are still talking and still consider each other friends,” a source said at the time “They aren’t in the same country for a while, which makes a relationship hard, but they are open to whatever the future might hold.”
