Jennifer's natural hair is curly and short, but the mother-of-two loves to experiment with hair extensions, which she more often than not wears during public appearances.

The star previously revealed to People that she feels at her best "when my hair is curly and I'm a little bit tan".
Alex Rodriguez's fiancée added that her trademark bun was inspired from her upbringing in the Bronx.

Jennifer has been keeping as busy as ever during the coronavirus pandemic, and recently released a new single, while at the same time working on her upcoming beauty range.

"I usually pray before she does her show and stuff, because she can get hurt in many ways."

The pre-teen also gushed about her mum during an interview with Mario Lopez for Access. "Well, my mom is just amazing," she said.
"She's such a powerful human being. It's insane. I don't even know how to explain it. There are so many adjectives that can describe her in so many good ways."
