Selena Gomez Single [VIDEO]: 'Come & Get It' Starlet NOT Dating, Back Together with Justin Bieber, Poses with Pregnant Mom Mandy in Adorable Baby Bump Twitter PHOTO

Apparently Jelena is NOT back together... at least according to "Come & Get It" songstress, Selena Gomez. In a recent radio interview with Boston's Kiss 108, the "Spring Breakers" beauty insists that she's still 100% single and ready to mingle... but Gomez's mom Mandy is most definitely unavailable! The 20-year-old starlet sent out an adorable Twitpic on Mother's Day evening (May 12), posing with her baby bump-flaunting mamma. Mandy is pregnant with her first child from Gomez's step-dad, Brian Teefey. Congrats to the happy fam!

Despite ongoing rumors that Gomez has rekindled a romance with her former "Boyfriend" crooner flame, it appears that she's definitely not in any sort of "exclusive" relationship with the Biebs. In a revealing radio interview with Kiss 108 on Friday (May 10), the DJ questions Gomez about her current dating sitch, asking, “So sometimes you may see a boy walking down the street and he says, ‘lets grab a ice-cream’... you’re available?” To which Gomez simply replies, “Yep!” The host then asks, “Completely available in every way?” And again the starlet responds, “Yep!” Check out the exclusive interview here...

Do fans think Bieber is disappointed?

But the Gomez fam does have some good news... Selena's mom Mandy is pregnant!

‏@selenagomez: "Hope all the amazing moms had a great day! I have the best momma in the world :)) I love you so much!"

Mandy kept this pregnancy rather quiet after experiencing a tragic miscarriage in 2011. This is the first time fan's get to see her adorable baby bump. This is Mandy and Teefey's first child together... looks like Selena's about to be a big sister! Congrats!
