Over the last week, pop singer Becky G has posted a few messages on Instagram that many believe are about ex-boyfriend Austin Mahone.

Becky G and Mahone broke up in August, supposedly because the two teenagers were too busy and work got in the way, reported E! Online.

However, several images that the "Break A Sweat" singer has posted on Instagram over the last week may hint that Mahone was the one who did not have enough time for their relationship.

On Sept. 18, the singer posted a message about love and heartbreak that got fans talking because it seemed like a direct message to Mahone.

"You want to come in my life, the door is open. You want to get out of my life, the door is open. Just one request. Don't stand at the door, you're blocking the traffic," read the message.

In May 2015, the singer told Ryan Seacrest that she and Mahone were having fun and their good friendship had developed into a romantic relationship.

"I've know him for such a long time and we started off as really great friends," said the 18-year-old. "We would always check in with each other ... We would always get in the studio together and, you know, you grow up and things happen and here we are."

However, in her most recent message, the Mexican-American star discussed friendship, specifically referencing the importance of staying together when times get rough. Could she be hinting at her breakup with Mahone?

"Real friends stick by you through the rough times as well as the good times. They will walk through the murky waters of trouble to the other side with you holding your hand. Those that are not real friends will tell you they will be there when you get back," read the message.

After her breakup with Mahone was revealed, the star assured her fans on Twitter that she was okay and that she had dedicated herself to her work.
