One Direction to guest star on iCarly

UK boy band One Direction will be guest starring on the fifth season of the Nickelodeon show iCarly. Niall, Zayn, Harry, Louis and Liam will begin shooting on Monday, and are set to perform their hit single "What Makes You Beautiful." Read the episode description below:

"Carly returns home sick after a trip and discovers that One Direction has accepted an invitation to perform on their web show. Not long after arriving, bandmate Harry becomes sick and we see Carly doting over him. Realizing Harry is playing sick for the attention, they hatch a plan to get him back in the group by telling him Gibby has become their newest bandmember."

This isn't 1D's first collaboration with Nickelodeon. The guys will be opening for Nickelodeon boy band Big Time Rush on their Better With U Tour, starting next month.

Josh Groban guest stars on last night's new episode of The Office

Last night on the new "Garden Party" episode of The Office, Josh Groban played Andy's younger brother Walter Jr. As it appears throughout the episode, Andy's parents seem more proud of Walter Jr., and he even replaces Andy with doing a duet with their father (played by Stephen Collins) in front of the whole office staff and the new boss at the garden party Andy was trying so desperately to prove himself at.

You can watch the entire episode of The Office below, and see Josh Groban singing with Stephen Collins at 15:50:
