Ariana Grande and Nathan Sykes' break up might be one of the reasons why the 20-year-old songstress has been stressed these past few days. Recently, Grande needed to put up with rumors of her feud with 'Sam and Cat' co-star Jenette McCurdy.

McCurdy previously expressed her disappointment with Nickelodeon's unfair treatment. Her complains were vague but fans were quick to assume that her rants referred to Grande. McCurdy also unfollowed her co-star on Twitter and did not attend the Kids' Choice Awards. She later explained the reason behind her actions:

"I was put in an uncomfortable, compromising, unfair situation (many of you have guessed what it is) and I had to look out for me. I chose to not go because sticking up for what is right and what is fair is what my mom taught me is ALWAYS the most important thing."

On the other hand, the 'Baby I' singer addressed the speculations about her paycheck through her Facebook account:

"I hate addressing rumors and I hate gossip but this is really bothering me. Jennette and I agreed upfront that we would be treated equally on this show in all regards (as we should be, considering we each work just as hard as the other on this show). The rumors circulating about our contracts and our salary not being equal are absolutely ridiculous and false," wrote Nathan Sykes' former girlfriend.

She again emphasized that her paycheck's not greater than McCurdy's: "I don't know who's putting these idiotic quotes out there but I thought I'd straighten it out and try to end this nonsense. As far as the show goes, I don't know what's happening because I'm not directly involved with the problem but I just wanted to address this one rumor in particular because I am NOT making more money than my costar, nor do I think I should be. So we can all move on and get out of our heads that this was a money thing cause I don't play like that at all. I am, have always been and always will be about equality and fairness."

Do you think Grande receives special treatment from Nickelodeon?
