Is justin timberlake selling his penthouse in secret?

Justin Timberlake and Jessica Biel's rumoured wedding may not have taken place this weekend, but the pop star's real estate relationship may be in for an equally big Change.

Indeed, celebrity house watchers are currently speculating that Timberlake and Biel have placed their Manhattan penthouse on the market. The apartment, which spans over 2,500 square feet, has been "semi-covertly available" for 71 days, Real Estalker reports.

The three-bedroom penthouse boasts a galley-style kitchen and two long glass walls that open onto a wrap-around terrace, complete with views of the Empire State Building.

Timberlake and Biel moved into the penthouse last year after selling off another apartment in SoHo. That condo went in July last year for $4.7m, less than the couple originally paid for it in 2008.

The pair will be hoping to have more like this time round: they picked up the penthouse in 2010 for $6.5m. The asking price now? A cool $7.65m - a profit that, surely, anyone would want to shout about.
