Update 2: A representative for Bravo has confirmed that John Mayer and the Backstreet Boys are no longer scheduled for the 1/28 and 1/29 editions of “Watch What Happens Live,” respectively. The cancellations are reportedly related to winter storm Juno.

As of press time, the appearances have not been rescheduled.

Savannah Guthrie and Al Roker will serve as the guests on the 1/28 show. Tony Goldwyn and Jennifer Nettles are booked for 1/29.

Update: While Bravo’s official “Watch What Happens Live” website still lists John Mayer and The Backstreet Boys for the January 28 and January 29 episodes, respectively, the press listings no longer feature the two acts.

According to the press website, the 1/28 episode will feature Savannah Guthrie and Al Roker. Tony Goldwyn and Jennifer Nettles are now listed for the 1/29 episode.

It is thus unclear whether they are still appearing. Headline Planet hopes to have an official update shortly.
