Blooper Added in Final Cut?

In the scene where Leo is taking Page on their 'first' (post accident) date, he gets her to eat chocolates from a box. In this scene, there is a moment where Paige asks whether he is attempting to give her diabetes or make her fat. A bit of food escapes her mouth as she delivers this line and it falls on her hair, face and Leo laughs....I believe this was an out-take and they just kept it in the film because it was cute.
The reason I think this is because Channing gives out a genuine sounding laugh and Rachel seems a little embarrassed. She also looks over her right shoulder in a 'gosh darn, silly me' manner as if playing cutsie to someone out of the cameras range...presumably the crew on set. What do you guys think?
