And Justin Timberlake and Jessica Biel made light of their new love of homelife as they joked about being out for the night on Friday.

'Thank you for allowing mommy and daddy to have a really good night out together,' laughed Justin, as he and Jessica took to the stage at the GLSEN Respect Awards in Los Angeles.

'With adults. Honey, look around, this is what adults look like. They do exist! They don’t smell like poopy diapers. …some of you do.'
