Ariana Grande performed at the 2015 Grammy Awards and for a young performer like her, she admitted to having nerves just before she stepped on the stage. However, the presence of her beau Big Sean reportedly helped calm her down. Moreover, her family is very welcoming of the rapper and is happy for the couple. 

Ariana's brother Frankie has nothing but good words to say about Big Sean. He described him as "a great guy" and "extremely normal," reports The New York Post. At the Grammy's, the 21-year-old songstress and the 26-year-old rapper came out for the first time as a couple, a move that made Frankie proud and happy for his sister. 

He said, "She was so wonderful and so happy and they looked great together. I was thrilled." 

Ariana performed the ballad "Just a Little Bit of Your Heart," which Frankie said left him and their mom sobbing. In fact, the 2015 Grammy's took on a more somber tone throughout the night with one ballad after another. 

"Luckily, Ariana was in the correct half of the show. I thought the first hour of the show was spectacular ... [but] I got bored out of my mind once Madonna was done," he added. 

Elsewhere, Ariana and Big Sean aren't keeping their romantic relationship down low. In social media, the two continue to profess their love for one another. In one of Ariana's tweets during the Grammy's, she said "thank you my babes for all the love n luck today. i love u w all my heart!" 

This tweet was then followed by "also thanks to my boyfriend for making me laugh thru the nerves/ unbearably awkward red carpet interviews. there is nothing weirder. i love u @bigsean"
