American pop singer and actress Selena Gomez reportedly misses former boyfriend Justin Bieber. The former Disney star feels she will never find true love again.

On July 10, the Baby hitmaker had announced on his Instagram account that he got engaged to Hailey Baldwin. According to Hollywood Life, the Come and Get It singer is worried that she can never replace the Baby singer.

A source told the website: "Selena fears that she will never have another love in her life like she had with Justin, she's worried that she'll never be able to find anyone that captures her whole heart and soul the way he did."

"Selena fell in love with Justin because he is the complete package. Selena finds Justin handsome, smart, sexy, insanely talented and incredibly successful, he is too perfect," the insider added.

"She has to remind herself all the time that as much as she loved him, and will always love him, that they broke up for a reason. As much as Selena knows that her relationship with Justin wasn't always healthy for her, it's very painful to see him moving on and so in love with Hailey. It makes her question how deep his feelings for her really were because it's not been nearly as easy for her to move on," the source shared.

"She still can't help but compare everyone else she might date to Justin. What they had was so intense, her feelings for him go so deep. The loss of their relationship has left a huge hole in her heart and she worries that no one will ever be able to fill it," the insider revealed.

"Selena wants to find the kind of love she had with Justin again but she fears it might be impossible, that it was a once in a lifetime kind of love and now it's lost. She tries not to think that way but deep down that's a huge fear for her, she worries she might be single forever."

Though Gomez has been silent about Bieber's engagement, she had previously revealed that she is unhappy with the constant scrutiny about her relationship with him. She told W magazine: "I'm so exhausted. I honestly am so done. I care about his health and well-being. But I can't do it anymore."

"To me it was: I'm 18, I have a boyfriend, we look cute together, we like that. Then I got my heart broken and I cared. Because people had no idea what was going on, but everywhere it was a million different things. I was kind of in a corner, banging my head against the wall. I didn't know where to go," Gomez added.
