Selena Gomez's Grandparents Share Her Intimate Childhood Photo Album

For the first time, Selena Gomez’s grandparents are speaking out to RadarOnline.com to reveal the truth about Selena’s drug use, secret rehab stay and life-threatening illness -- and why they say they’re worried their little girl could become another victim of fame.

Despite Selena’s early success at child modelling pageants, her grandfather Ricardo Gomez tells Radar, “it never crossed our mind that her getting famous could happen like that.”

When baby Selena was born, “We were very happy because that was our first granddaughter,” Ricardo says.

Selena even brought on-off boyfriend Justin Bieber to meet her grandparents. “We like Justin,” Ricardo says, although his current behavior seems out of character.

Selena’s grandparents nicknamed her and Bieber “flaca” and “flaco,” Spanish for “slim.”

He bonded with the family during visits by eating Selena’s grandmother Mary’s Mexican cooking and playing video games on the rug.

When Selena comes home to Texas, it’s “just to relax and stay away,” Ricardo says.

She misses that family time,” Selena’s grandfather claims. Her rise to fame “was just so quick and sudden,” he says, and she’s been struggling to adjust.

Selena’s dad Ricky now works at a local CVS in Texas.

Her grandmother Mary and grandfather Ricardo say she should take a break from the bright lights of Hollywood to recharge and refocus.

Ricardo and Mary’s Texas fireplace is still covered in doodles done by a young Selena.

Now, “we tell her we sit here and watch the TV and we watch all the handwriting she did,” Ricardo says. “We remember the good old times.”

Raised Catholic, Selena has been getting back to her roots and worshipping with Justin Bieber’s pastor in recent weeks.

Photos of Selena as a child star still hang at her proud grandparents’ home.

Despite Selena’s fame, they still live in a humble Texas home.

Ricardo says he has three rules for his granddaughter: One, “Have god in your life first.”

Two, he says, is, “Be yourself.”

And third, Ricardo explains, is “Don’t let things get over your head.”

Selena comes back to Grand Prairie on occasion, but Ricardo says they keep such visits “quiet.”

The last time they saw her was at a concert in nearby Dallas.

Their humble home is a far cry from Selena’s luxe L.A. digs.
