While there’s no new music on the horizon (that we know of, anyway), Lance Bass, Joey Fatone,Chris Kirkpatrick and Justin Timberlake banded together to celebrate JC Chasez‘s 40th birthday. Timberlake shared a picture of the boy band’s get-together with his 33.3 million Instagram followers late Monday writing, “JC’s 40th… And, if you don’t know now you know…”

Chasez is the second member of ‘N Sync to reach the milestone age. Kirkpatrick is 44, while Bass, Fatone and Timberlake are all in their 30s. Kirkpatrick poked fun at Chasez on Twitter, sharing an old photo and writing, “Happy birthday @JCChasez! Welcome to the old man club!”
