The 65-year-old was spotted with her daughter – and granddaughter Suri – in the Big Apple this week. She has travelled from Ohio to be at the Dawson's Creek actress' side.
The three generations of Holmes girls took a trip to the Chelsea Piers complex, seemingly in good spirits.
Katie looked happy and relaxed the day after she reached a divorce settlement with her estranged husband.
The 33-year-old looked pretty in a denim dress with bright green ballet pumps, while her six-year-old wore a floaty little frock in all the colours of the rainbow.
Katie's attorney confirmed on Monday that the brunette star and Tom had come to terms.
Jonathan Wolfe said: "This case has been settled and the agreement has been signed."
Speaking to TMZ, he added: "We are thrilled for Katie and her family and are excited to watch as she embarks on the next chapter of her life.
"We thank Tom's counsel for their professionalism and diligence that helped bring about this speedy resolution".
A key element was said to be Suri's living arrangements – with both parents agreeing Suri should live with her mother.
It's a little princess!
