Selena Gomez, 21, displayed an emotional outburst towards boyfriend Justin Beiber or Demi Lavato on social media platform Instagram posting several pictures and a video with cryptic messagages in the captions.

It all began on Monday, when Gomez posted a series of pictures with captions which hinted of her relationship with Bieber. She seems to be caught in on-again-off-again relationship with Bieber that is also causing problems between Gomez and her friends.

Gomez first shared a video of herself playing piano which she captioned, "I don't know. I'm on my way you know."

Then she posted an upside-down picture of her fans motivating messages, captioning it as, "You're always listened to"

Afterwards, she updated a picture of herself on a beach with the caption, "and usually always right." Then she posted a screenshot of her phone with text message from unknown sender, which read, "I just want to give you a hug and remind you how special you are." To which she captioned, "That's who you wanna wake up to. #promise."

Gomez's instagram followers instantly speculated about her relationship with Bieber claiming that the couple are back together.

According to eonline.com, a source recently revealed that Justin Bieber is on the guest list to attend Gomez's 22^nd birthday party on 22^nd July, even though her friends tried to convince her otherwise.

"No one wants [the Biebs] to go. All her friends want him out of the picture and just want her to have a relaxing birthday with no trouble and they think he's going to dominate her attention," a source told E! News.

"She doesn't seem to care that he spends time with other women and isn't always honest with her. She's hypnotized. Her friends just want her to enjoy herself for her birthday, but if Justin attends it might complicate matters."

On the other hand, those cryptic messages can be her way to reconcile with her gal pal Demi Lavato, who recently stopped following her on Twitter. The two Disney stars seems to have some problem between them.

According to HollywoodLife.com, a source told, "Demi doesn't need any extra drama, she's learned from her own recovery to lose the people that bring her down and Selena is too much of a headache.

"The unfollowing of Selena is sending a message that Demi is p*** ed. She is sick of Selena's boy-who-cried-wolf mentality."
