They have been having fun in New York.

And on Sunday loved up couple Kate Upton and Justin Verlander flew back into Los Angeles.

The 22-year-old supermodel and her Detroit Tigers baseball superstar kept it simple, arriving with little fuss and wheeling their own luggage. 

And the pair looked fit and ready to go as they strolled across the concourse at LAX to a waiting hummer limo rentals after the five-hour flight from JFK.

The gorgeous blonde appeared cosy in a green sweater teamed with black skinny jeans tucked into black high-heeled ankle booties.

Without make-up, her beautiful natural complexion was clear to see helped by the fact she pulled her hair up into a top-knot, giving everyone a good view of her face.
