Scarlett Johansson's infant son Cosmo has a newfound obsession, and it is blowing his mother's mind!

According to Cosmo's mother, the discovery of feet has been a "life-changing" experience for the boy as he couldn't go a day without staring, touching, or chewing on his little toes. In her words:

"It's just unbelievable. I mean, can you imagine you never realized you had feet and then you looked down, and there they are? You're like, 'Whoa.' "

Discovering new things seemed to be part of the family as "The Avengers" star's daughter, Rose Dorothy, recently realized that her mother has always been a famous actress.

Since understanding the way animated movies work, the 7-year-old has been excited to watch the entertainer perform in "Sing 2," which will be released on December 22.

Days after her grandson was born, the worried matriarch would call the "Saturday Night Live" writer to confirm if the couple would truly name the boy Cosmo.

The proud grandma even suggested that the parents change their son's name to "Cosimo," however, neither entertainer would back down.

Eventually, the older woman stopped pestering the lovebirds once she realized other people were bearing her grandson's unique name.

The "Don Jon" Star Is Not A Fan Of Social Media

Last month, The Blast reported that Johansson wasn't fond of sharing her private life on social media. The Tony Award winner liked to keep things low-key despite her gorgeous appearance.

In 2011, the mother-of-two confessed to sources that she had better things to do than share details of her life on the internet.

Rather than post pictures of herself or update fans about her daily routines, the "Ghost in the Shell" actress used her fame to create awareness for her passionate causes.

Although the Marvel star wished to keep her life away from the cameras, it was nearly impossible as most wished to know more about the sexy Avenger.
