Selena Gomez and Justin Bieber, who have recently reunited after breaking up for a brief period of time, may be celebrating the "Come and Get It" singer's 21st birthday on July 22.

Selena Gomez and Justin Bieber have had an on/off relationship for some time, but the two seemed to be doing just fine.

Selena Gomez, when interviewed on New Music Live in Toronto, Canada, was asked about her big day that is coming on July 22, which will be when she turns 21 years old.

Justin Bieber's twitter update for the past few days have been about celebrating her little sister's birthday, and many are speculating whether Justin Bieber and Selena Gomez will be celebrating the singer-actress' birthday together too.

Selena Gomez said at the interview, "Obviously in America, 21 is 'the age,' so I am going to actually have a really big party. I want to have a great party. I'm going to invite my friends and my family, and I'm definitely going to celebrate."

Many are wondering if Selena Gomez's "friends" may also include her boyfriend, Justin Bieber.

Selena Gomez also said to ET Canada, saying "My family from Texas, my friends [and] my cousins are flying in. I will have some of my best friends in L.A."

It seems that if Justin Bieber ends up being in L.A. on Selena Gomez's birthday, Justin Bieber and Selena Gomez will be spotted together again.

Selena Gomez's newest single, "Come and Get It," has achieved tremendous success, and the singer plans to release her forthcoming album "Stars Dance" this summer.

When mentioned about her age, Selena Gomez reportedly said," I feel like sometimes I am 15 in my heart. You know, sometimes I just go in waves of being a child and being an adult. It's awkward, I am growing up. I am just trying to figure out who I am."
