They were seen enjoying a sun-filled vacation in Mexico.

But it was back to reality for Heidi Klum, 44, and boyfriend Tom Kaulitz, 28, as they returned to LAX from their holiday on Thursday night.

The supermodel looked relaxed as her much-younger beau stayed by her side on their way out of the airport.

Heidi was styled in a black, Gucci sweater adorned with silver studs.
