Now, Noah has taken to the comment section of his girlfriend's Instagram to express how much he loves her, and it is super sweet.
Posting a photo of herself in French Polynesia holding a piece of coral, Alexis wrote: "Teaching the kids today about coral restoration. Let’s save our reefs @coralgardeners."
Alexis already publicly declared her love for Noah in an interview with Entertainment Tonight last month.
"I love that man. He's amazing," Alexis told ET.
"God, his spirit. He's so vibrant and passionate about everything he does.
"He puts 100% of himself into everything and his heart is gold."
Ok, these two are almost too cute handle.
