Who's that girl?

Tom Cruise and Nicole Kidman's daughter Isabella Cruise was spotted at a rare public event this week ... and boy does she look different!

Isabella Cruise, who is 23 years old, attended the Tyler Shields' Decadence exhibition at the Maddox Gallery in London on Feb. 3, 2016.

Isabella stepped out in an all-black ensemble, featuring a billowy black cardigan, a black top and pants and simple black boots.

She donned minimal makeup, but rocked dark brown lip liner around her nude lips.

The overall affect kept all eyes focused on her silver, circular nose ring.

Isabella also debuted a new short, blonde bob.

As a hair dresser, it's not unusual for Tom Cruise's daughter to change up her look often.

Over the years she's rocked dark brown locks, orange hair, blue hair, a shaved head and even a pixie!

This was the first public outing for Bella -- as her friends call her -- since she privately tied the knot in 2015.

Woman's Day Magazine reported that Isabella married Max Parker in a small ceremony in London at the post Dorchester Hotel on September 18, 2015.

It was reported that Nicole Kidman and Tom Cruise weren't on hand at the marriage celebration. However, the Daily Mail reported that Tom Cruise funded the entire day so Isabella, Max and their friends could enjoy the day all together.

Even though Nicole Kidman and Tom Cruise -- and even Bella's brother Connor Cruise -- didn't attend the wedding, they both approve of the union and are happy for their daughter.

Isabella and Max, who dated for about a year, apparently met through friends and both live in London.
