Lightning usually only strikes once in a family, as in if one sister is beautiful the other usually is not as attractive.
But this is not the case when it comes to Hollywood's leading ladies. Often the sister is just as gorgeous as the A-lister is.
And they are brought onto the red carpet while in couture gowns to prove this point. Other times, they can be spied on the star's Instagram page.
Think of Penelope Cruz and her doppelganger Monica Cruz - who has served as her stand in at times.
And then there isCameron Diaz and her photogenic sister Chimene Cain.
And sometimes the star has a twin or look-alike who is in the business as well like the Olsen sisters or the Fanning ladies.
Here is a look at the ladies who looks the most alike.
Hint: some of these ladies have Hollywood 'it' woman Meryl Streep as a mom.
PENELOPE CRUZ AND MONICA CRUZ

Monica looks so much like Penelope, in fact, she stood in for the silver screen goddess during scenes for Pirates Of The Caribbean: On Stranger Tides in 2010.
In 2023, the 50-year-old Oscar-winning star talked about her 47-year-old sibling.
When asked whether she and Monica influenced each other's styles, Penelope said: 'Yes, a lot, to the point of, you know, taking a lot of clothes from each other's closets.
'Sometimes wearing exactly the same thing when we were little girls.'
Cruz then said that she and Monica would hide 'in the bathroom together and sitting on the floor with magazines and drawing on top of the designs and changing the designs.'

On Friday Dakota talked to E! News about Elle. 'We have a very playful relationship, but we're not competitive,' Dakota said. 'We were never competitive growing up.'

Emily called her sibling 'fearless.' She told Women's Health in 2007, 'In seventh grade this kid didn't invite Zooey to his bar mitzvah. And she went right up to him and shouted, "Why didn't you invite me to your bar mitzvah?" I just love that... I would have called my mom crying.'
