Neither can he, it seems.
Yes, the 35-year-old pop star's hit 2006 electro R&B song "SexyBack," one of his most successful singles, celebrated its 10th anniversary earlier this month.
When asked about the milestone, Timberlake told E! News' Marc Malkin exclusively, "That makes me feel old."
"Life has changed, a lot!" he added.
"SexyBack" is the first single released from the pop star's second studio album, FutureSex/LoveSounds.
