Uhhh, is this Hailey Baldwin sending a message to Selena Gomez, a la Julia Roberts back in the day when she wore the "A Low Vera" tee as a shade to her boyfriend's (now husband's) ex? The blonde model wore a sweatshirt emblazoned with the word "Unavailable" yesterday as the couple ran errands. Is it a message to Selena Gomez to back off? Is Hailey feeling threatened by the pop star's new single "Lose You To Love Me," which was clearly an open letter or sorts to Justin? The hit song seemed to destabilize JB a bit, forcing him into a solo retreat to get his head together and regroup. And now that the couple's back together, they do look a little "off," right?

That said, Hailey's really trying to keep her hubby's attention -- check her out in leather leggings she wore last night for a dinner date to get burgers! The couple were with Justin's mom Pattie and Hailey's parents and Kim K's BFF Jonathan Cheban. Weird mix!
