Ashlee & Pete's New York Arrival

Jetsetters Ashlee Simpson and Fall Out Boy frontman boyfriend Pete Wentz arrive in the Big Apple via a flight from Los Angeles on Thursday morning.

Not able to stay in one city for every long, Pete, 27, and Ashlee, 22, held hands as they made their way through JFK airport.

On Monday, the canoodling couple made a trip to Las Vegas, where they were spotted snuggling and kissing.

The pair then flew back to Los Angeles shortly after, making a quick shopping trip to Barneys New York in Beverly Hills on Wednesday (inset).

Thursday is a brand new day. New York City, get ready for the Ashlee-Pete-fest!
