Justin Timberlake’s Too Pooped To Party

Justin Timberlake is far from the hell-raiser he used to be. In fact, he could pen about “bringing nap time back!”

“He’s just too tuckered out from being a new dad to 4-month-old son Silas!” said an insider.

The singer-actor has been a homebound husband at the side of wife Jessica Biel since Silas arrived in April.

“Jessica actually gives Justin a long leash if he wants to hit some nightclubs with his pals, but he pretty much turns down invitations now,” a friend dished. “He’s worn out!”

Part of the pop star-turned-poppa’s new reclusiveness is his sense of duty, but the rest is pure exhaustion.

“He loves being a new dad, but Justin says taking care of an infant is like a workout routine on steroids!” said the source.
