Dessert, please! Joe Jonas and girlfriend Demi Lovato dined at the Cheesecake Factory at The Grove in West Hollywood. The couple split a few appetizers – then moved on to the main course (cheesecake!) afterward. “They were adorable,” an onlooker says. And Jonas even Tweeted his approval of the restaurant, writing to fans that “I love the cheesecake factory. :)” Coincidentally, Miley Cyrus stopped into the eatery that night after attending a Make a Wish function at the outdoor shopping center.
