Lindsay & Sam Get Bus-y!

Talk about a shock - yesterday, not only did Samantha Ronson smile at us as she stopped by the set of Labor Pains to visit her pal Lindsay Lohan, but she even made a point of holding Lindsay's hand in full view of the cameras!

In fact, we spotted the dynamic duo horsing around on the set all day long. Frankly, we're a little stunned to see Lindsay and Sam acting so affectionate after the flap over last time - but judging by how positively Lindsay responded to Sam's attention, we're pleased as punch by their bravery!

(And yesterday Lindsay needed the lift more than ever - she was filming practically all day long, including one scene which required her to get on and off a bus!)
