A 43-year-old mum says she’s often mistaken for her teenage son’s sibling.

Marcela Iglesias, who spends £740 a year on Botox to maintain her youthful looks, is flattered by the compliments.

She said: “When we go out together to concerts or shopping - people think I am part of his gang.

“They can't believe I am his mother. I am flattered, it is a massive compliment.”

While Marcela’s 19-year-old son Rodrigo used to cringe at the comparisons, he’s learned to love them.

The mum-of-one, from Los Angeles, US, explained: "My son used to get embarrassed when he was young but he loves it now.”

Marcela added: "I guess it is because I am not a typical mum. I am trendy and fashionable.

"We sometimes share clothes, I have some unisex jackets which look great on him.

"Rodrigo says I don't look like a 'normal' mum.

"I am a little crazy and extreme but Rodrigo doesn't mind. I don't act my age!”

The mum even spends time with her son’s friends, which is probably why some think she’s in their “gang”.

The mum-of-one has always had a very close bond with her son

Marcela explained: "I love hearing what the younger generation have to say, because they are our future - so always catch up with my son's friends.

"I find that people forget how to live their life and worry too much with age but I do my best to live life to the full."

The mum added that she has a very close bond with Rodrigo, who she shares similar interests with.

She said: "We are incredibly close and always together. We go shopping a lot together as he gives great fashion advice.

"Our bond is more like siblings rather than mother and son so it is not surprising that others are mistaken."

Marcela gets Botox to maintain her age-defying looks

Many ask Marcela for the secrets behind her age-defying looks.

And according to the mum, you don’t need to have any plastic surgery.

She said: "I started getting Botox and fillers in my thirties. I get it to maintain and enhance my natural looks.

"I have also had stem cell therapy which meant I was injected with 30 million stem cells. It is to repair and generate healthier and new cells.

"But I have never had any other cosmetic procedures - I definitely think less is more."

Marcela added: "I am not against surgery but I do think if you get too much - it can make you look older.

"However, I would be open to a face lift in the future if I need one.

"I also lead a stress-free life and quit smoking which is a key ingredient to looking younger.

"I lead a healthy and balanced lifestyle which is always good for your appearance."
