According to a nosy onlooker at the Palm Beach airport in Florida, the To All the Boys I’ve Loved Before actor, 23, and the social media influencer, 22, were looking extremely loved-up.
The source told Us Weekly: "He picked her up as she was on my flight. He was waiting for her at baggage claim.
"He kissed her on the head, [and] they were holding hands and hugging."
Did you need more evidence?
Don't worry, we have some.
Yet ANOTHER source told Us Weekly that on September 25th they saw Alexis and Noah looking all sweet and in love while leaving a restaurant in West Hollywood.
"He was with a group of five people: two girls and two guys, plus him," the eyewitness 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."
But wait, WE HAVE MORE.
A third source then spotted the couple going for a shop at Whole Foods in downtown Los Angeles on Thursday, Septemeber 26th.
One source can seem kind of dodgy, but three? That sounds like proof to us fam.
To add to the overall cuteness, Alexis posted her first 'couple photo' with Noah by sharing a screenshot of a seriously sweet text exchange, as well as a photo of a hand cupping her face.
Prepare yourself, because this is TOO MUCH.
Leaving the photo captionless, Alexis posted this male looking hand holding her smiling face.
The next photo is a text message conversation with presumably Noah, and BRB we're just going to go cry now.
"You know what makes me think of you?" the first texter (we're going to guess Noah), reads.
"What", the blue bubble says.
"Everyone. And everything. All the time. You are this gentle layer over my reality."
Dear lord if this isn't couple goals then we don't know what is.
