Just a day after Justin Bieber shared a series of intimate photos taken with his alleged new flame Yovanna Ventura via Instagram, Selena Gomez now posts a cryptic message targeting her on-and-off again boyfriend.

The snapshots of Bieber and Ventura, who have recently been spotted together on numerous occasions in public, emerged online on Tuesday. One of the pictures sees the 18-year-old model straddling behind the Canadian pop star with her arms around his waist and hands under his shirt, as he sits in front of a keyboard in his recording studio.

The 20-year-old singer then posted another image that shows him making a silly face with the caption "sleepy," before taking a picture of Ventura actually sleeping in his studio. "Fell asleep in the stu," he wrote the following caption.

In response, the "Come & Get It" hitmaker took to her social media account on Wednesday, July 9, to seemingly let Bieber know how she feels and her lesson learned. The message reads: "On valuable life lessons she has learned: 'The moment you compare yourself [to another woman], it weakens you, and I'm not here for that. Once you know that reality [and] claim your space, your life becomes easier.'"

"#zoesaldana #womenempowerment you are all so beautiful the way YOU are," she captioned the Instagram post. "No bigger or smaller. You all inspire me."

On the same day, the 21-year-old singer sparked boob job speculation after she was seen wearing a black boob-revealing low-cut tank top in New York City -- she was photographed when she was leaving lunch at The Bedford restaurant.

However, Gomez's plastic surgery rumors were immediately denied. "This is a rumor that comes up all the time," a source told E! Online. "She did not have any work done."
