Justin Timberlake looked rather grumpy during  a ride home with his bride-to-be.

Despite having a lavish meal at a San Juan  restaurant in Puerto Rico, being chauffeur-driven around and sitting next to one  of the world’s most desirable women, he failed to raise a smile.

Perhaps The Social Network star was missing  his father today, as he is currently on location.

Justin tweeted: ‘Happy Father’s Day  to all  of the Dads, Daddies, Pops, Big Poppas, and Pa Dukes out there!!  Have a great  one!! #FathersDay.’

The singer-turned-actor is said to be filming  thriller Runner Runner with Ben Affleck, a twisted tale which  will follow the  intricate world of online gambling.

Whether the shooting will interfere with his  rumoured summer wedding to Jessica Biel remains to be seen.

The private pair have been somewhat coy about  revealing information regarding the day they intend to get hitched.

Former N-Sync bandmate Lance Bass stressed  that even guests would be unlikely to know plans prior to the big  day.

He toldEntertainment Tonight Canada: ‘You never know. We might do a little improv a capella (at the  wedding). I’m  sure when the wedding comes about, no one is going to know until five seconds  before.

‘I’ll probably cry. That’s what I do  at  these things. If I have to do a speech, it’s something that means so  much…  The tears start coming.’
