Nicole and Joel Aloha LAX

They've had their fill of ukuleles and hulas -- Nicole and Joel have said aloha to Hawaii and returned to glamorous Glendale.


TMZ was at LAX last night as the vacationing soon-to-be-parents Nicole Richie and Joel Madden returned from their trip to paradise -- and boy did they look thrilled to be back.

Never cracking a smile -- and Nicole hiding her belly behind a pillow -- the dour twosome worked their way past the paps to their waiting SUV. Welcome back!
