Katie Holmes will do whatever it takes to keep her little ballerina, Suri, happy ... even if that means lugging around a massive Angelina Ballerina doll.

Angelina Ballerina is a pink mouse who likes to dance ballet ... and wears a pink tutu, pink ballet shoes and a pink ribbon. Pink overload! The cute character originated in the UK back in the 80's and is currently a popular kids' TV show.

Good thing Tom Cruise's wifey is such a good mom and willing to carry her little girl's pricey mouse around town.
