Selena Gomez posted a picture on Instagram urging her school-going fans to make friends with children who are being bullied, sparking gossip among her social media followers that her rough experience with pregnant, rehab and lupus rumors has made her more aware of bullying.

Last week she was spotted cuddling in a new picture with Justin Bieber on his Instagram page, confirming reports the couple is back together.

"Justin is getting really healthy, he wants to look good for Selena so he's working out a lot, they're both on a health kick," a source told Hollywood Life. 

"They're detoxing from all the partying and negativity right now. He's been hiking every day, that's his new favorite thing. And he's getting up early because he's not out partying all night, he's just been at home chilling with Selena."

Selena Gomez posted a photo of herself on Instagram getting emotional while delivering an acceptance speech at the Teen Choice Awards, leaving many fans wondering if rumors of her having lupus, going to rehab and being pregnant with Justin Bieber's child contributed to her reaction.

Earlier, she posted a picture on Instagram of her and several friends holding up signs promoting donations for children's charities-could the "Slow Down" singer feel charitable after encountering her own experiences with rumors of her being pregnant and attending rehab for lupus?

She was also spotted in Instagram pictures with businessman Tommy Chiabra, prompting rumors she's dating the mystery man as a rebound following her break up with ex-boyfriend Justin Bieber and rumors she was pregnant and was being treated for lupus in rehab.

Two weeks ago, she posted a picture on Instagram of a powerful Howard Thurman quote.

"There is something in every one of you that waits and listens for the sound of the genuine in yourself," part of the quote reads.

"It is the only true guide you will ever have. And if you cannot hear it, you will all of your life spend your days on the ends of strings that somebody else pulls."

Could she be referencing Justin Bieber and all of the drama surrounding rumors of her being pregnant, having lupus and attending rehab?

Selena Gomez also posted a picture on Instagram featuring a new tattoo she received with Arabic writing, leaving her fans wondering if it is related to hardships experienced during rehab, lupus treatment and rumors of her being pregnant.

She posted a mysterious picture on Instagram of a text message she received saying "I just wanna give you a hug and remind you how special you are."
