Looks like Justin Timberlake and Jessica Biel are going all out for his 38th birthday. The Man of the Woods singer enters the second-to-last year of his 30s on Jan. 31, but since he has to work, he and Jessica planned to go out the night before instead. But before the party even got started on Wednesday night, Jessica dozed off in the car, and Justin hilariously recorded himself singing "Happy Birthday" to himself in a whisper. After waking up, Jessica laughed and said, "I'm just preparing for our big night out." Partying as adults — and especially as parents — is an ongoing struggle. Try not to go too wild, Justin!
