Check out Denise Richards in a colorful summer dress and flip flops at LAX Airport following a flight from Montreal yesterday. 

Denise has reportedly revived her romance with ex-boyfriend Richie Sambora. She briefly dated the rocker in 2006 following the breakdown of their marriages to actors Charlie Sheen and Heather Locklear, respectively.

The 39 year old actress is set to join the cast of the football comedy "Blue Mountain State" in a recurring role as a woman named Debra.
