Alice Vasquez is living proof that age is just a number.

The Californian babe regularly passes as her daughter’s sister as the pair hang out together.

So it must come to a big surprise to strangers when they realise that the 39-year-old isn’t just a mum – she’s also a grandma too.

AGE IS JUST A NUMBER: Alice could pass for a woman in her 20s

Alice rivals Gina Stewart and Carrie Hilton for the title of the “world’s hottest gran”.

The yoga teacher fell pregnant with her first born when she was 16-years-old.

Three years later, she welcomed her second child into the world.

Her kids followed similar paths to their mum, both becoming parents in their early 20s.

OH MY BOD: Many are blown away by Alice's youthful appearance

While some find it difficult to wrap their head around the fact Alice is a gran, the family takes it in good stride.

She told Daily Star Online: “My daughter thinks the attention I get is fun.

“We motivate each other to live our best life despite the pressure of people judging us.

“People think we look like sisters and really think we had a hard life or some drama.

“It’s nothing like that... we just both fell in young love, and had kids young. It’s nothing to be ashamed about.”

The fitness fan refuses to let her grandma label get in the way of her living her life.

She regularly goes clubbing, where she is hit on by men who are 10 years younger.

Unsurprisingly, they are shocked when they discover she has children and grandchildren.

But bizarrely, Alice believes that some of them actually find it a turn on.

MAKING A SPLASH: On nights out, Alice often attracts the attention of younger suitors

She added: “When men find out I’m a gran, they are instantly amused by the title. They always want to know more about me.

“Obviously I don't look like a grandma - and I actually think men find it hot!”

While Alice has dated some toy boys in her time, she has now settled down with a man she dated in her 20s.

The pair have been in a relationship since 2016 and are both living in Las Vegas.
