By Sarah Bull. But it seems that Jennette McCurdy's out of office activities may have led to the unfortunate early end of the Nickelodeon programme. Production on the show has reportedly stopped and it is unlikely to be renewed for a second season following selfies of Jennette, 21, wearing just her underwear being leaked on the internet. But there are also claims that the show has not been renewed because Jennette, who skipped the Nickelodeon Kids' Choice Awards last weekend, has fallen out with the network over pay - and is upset that her co-star Ariana Grande earns 'way more' than her, TMZ reported. The show has not been renewed for a second season.
