Ariana Grande has had a rough week in the love department. On Monday, her ex-boyfriend Jai Brooks posted a long, very public rant about their breakup -- and the young singer was in "utter shock" in the aftermath. Lucky for her, there's one special person who has her back no matter what: her co-star on "Sam & Cat" and real-life friend, Jennette McCurdy.


Ariana took to Twitter today to post this unbelievably sweet note she received from Jennette.
