Tom Cruise's estranged daughter, Suri Cruise, is all grown up.

Suri, who Cruise shares with ex-wife Katie Holmes, stepped out with a friend in New York City Thursday as she celebrated her milestone birthday.

Photos published by Page Six and the Daily Mail showed the teen sporting a denim jacket, brown shirt, jeans and black shoes during the outing.

Suri could be seen holding a small pink umbrella over her and her pal's heads as she carried what appeared to be a birthday gift in the other hand.

Later in the day, the teen was photographed picking up flowers at a local flower shop before celebrating her birthday with her mom, who was seen running errands across town.

Suri's 18th birthday came as Cruise continues to film a new "Mission: Impossible" movie in the U.K.

In photos shared by People, the now-61-year-old Hollywood superstar was spotted running down a street with fake blood on his clothes.

Cruise reportedly has been estranged from his only biological daughter since he and Holmes finalized their divorce in 2012.

It was reported at the time that the actress was awarded sole custody of then-6-year-old Suri, while Cruise got "meaningful" visitation rights.

However, Page Six reported earlier this month, citing an unnamed insider, that Cruise has not seen Suri in 12 years.

Suri was last seen in public with her dad during a trip to Disney World in Florida in July 2012.

The father and daughter duo were photographed spending time together in a pool during the outing.

Following the divorce, Suri has lived with her mom in Manhattan, where they're often photographed together.

Though she's now 18 and a legal adult, an unnamed source told the Daily Mail that Suri has no plans of meeting and having a relationship with Cruise.

"Suri will not have any contact with her father, despite being 18, and even if he called, she would not answer," the insider claimed.

"He does not exist to Katie or Suri, and his daughter does not want to rely on him for anything. She feels that she has one parent and that is her mother."

While the teen is still figuring out her professional goals, the source said Suri does not wish to follow in her famous parents' footsteps and become an actress.

"She's currently weighing up her options for the future," the source revealed. "But she plans on remaining a private citizen."

Cruise also had two adopted children -- Bella, now 31, and Connor, now 29 -- from his marriage to Nicole Kidman.
