The bubble life is over -- so it's back to the couple life for Kendall Jenner and Devin Booker.
The two have been inseparable since Devin's Phoenix Suns were bounced from the NBA Bubble last week ... picking up their romance right where it left off.
Check out 23-year-old Devin and 24-year-old Kendall running errands in Malibu Monday -- scooping up a brand new dog bowl for DB's pooch, Haven.
They're wearing masks! The dog's on a leash! They're doing everything right!
Remember, Devin left the Orlando bubble on Friday -- immediately hit Nobu for a fancy reunion dinner with Kendall on Saturday night.
