Ariana Grande and Jennette McCurdy star in Nickelodeon’s Sam & Cat, a crossover spin-off/sequel of both iCarly and Victorious. It stars Jennette McCurdy as Sam Puckett (from iCarly) and Ariana Grande as Cat Valentine (from Victorious). Basically take a couple of hotties from two now-defunct Nick TV shows that weren’t the main characters (Miranda Cosgrove from iCarly and Victoria Justice from Victorious), put them together, and you have another hit! Check out Sam & Cat at Nick.com for more information.
Sam Puckett (Jennette McCurdy from iCarly) has been touring the West Coast by motorcycle since the end of iCarly, and stops in Los Angeles. She witnesses Cat Valentine (Ariana Grande from Victorious) being thrown into the back of a garbage truck, and rescues her. They become friends, and Cat convinces her to become roommates after Cat’s grandmother moves to a retirement home. To make money, they form an after-school babysitting business that leads them into a series of comical adventures, rather than getting traditional after-school jobs. [Wiki]
