Where's Hailey?

Justin Bieber hit up his usual Wednesday night haunt Hillsong Church last night but his wife Hailey was conspicuously absent. Of course the two bond over their faith and both are church members so maybe Hailey had to work or stay home and get her beauty rest for an early-morning gig today.

Justin appeared to be in good spirits as he fist-bumped fellow churchgoers and danced his way to his car after the service. And exiting the service right after JB was none other than Lana Del Rey! The singer often attends when she's in town but when Hailey finds out Lana was there last night, will jealousy kick in???

Bieber had another new companion with him -- his Drew sticker-covered notebook. Or is that a laptop? He's bringing it with him EVERYWHERE these days! Is he working on music during church service? Writing a book? Keeping a real-time diary? Omg, what we'd give to read that!
