They look happy and it's nice to see him touching her (so I don't agree with the Nick doesn't look happy comment.) And she is beeming. I will say this though:
a) THIS IS THE BEST I'VE SEEN HER LOOK IN YEARS STYLE WISE. WOW.
b) At least they are being someone more adult about it than other couples who take the "we want our privacy thing" too far. At some point, when you keep denying a relationship, I just don't think that is healthy.
All the best and hope it works out for them!
