Mischa Barton was really partying like a rock star last Thursday night in NYC. Reportedly, the former “O.C.” actress got so carried away that she ended up upchucking on the street — but went right on carousing.

Fellow scene queens Kirsten Dunst and Jamie-Lynn Sigler were hanging with the Keds model at the Anchor in NYC.

A witness described the scene to Us magazine’s Web site: “They were partying, going crazy. At one point, Mischa suddenly ran out the door and threw up outside. Jamie-Lynn ran outside after her, but it wasn’t a big deal. They were laughing.”

After the incident, the source recalls, “They just went back inside and continued to party” — ultimately staying on past 3 a.m.

Now that’s what we call dedication.

New Spelling Production

A Hollywood dynasty has a new heir. Tori Spelling gave birth to a son, Liam Aaron McDermott, on Tuesday. Dad is actor Dean McDermott.

Liam clocked in at 6 pounds, 6 ounces, per a rep. His middle name is in honor of Tori’s father, the late, great TV mogul Aaron Spelling.

And, as Scoop! reported Wednesday, the blessed event is bringing even more joy to the Spelling family, in the form of a reunion between Tori and estranged mom Candy. The mom-and-daughter duo have agreed to end the rift that has grown between them since Aaron’s death.

“Words can’t describe the joy and elation I feel at this truly happy event,” Candy gushed to People magazine’s Web site. “I am looking forward to doting on my new little grandson and all the memorable fun that comes with it.”

Congratulations to the happy family!

Angelina Adopting ASAP

(AP Photo) Angelina Jolie went to Tam Binh orphanage in Ho Chi Minh City on Thursday, March 15, to adopt a 3-year-old boy who has been living at the orphanage since he was abandoned at a hospital as an infant, according to adoption officials. 

Meanwhile, another celebrity clan is also getting ready to welcome a new member. Tuesday, a Vietnam adoption official confirmed reports that Angelina Jolie’s adoption of an unnamed 3- to 4-year-old boy from the country was being fast-tracked.

The very next day, the actress — who is adopting as a single parent according to Vietnam law because she and partner Brad Pitt are unmarried — landed in Vietnam with son Maddox, 5.

According to a Vietnamese official, an adoption ceremony will be held today, followed by a U.S. consul meeting and a last review of paperwork. The thank-you-drive-through process could be completed by this weekend.

But while Angelina’s fame may have helped her cut through red tape (“A celebrated person is certainly treated a little bit different from others,” adoption official Vu Duc Long has conceded), a report that the Oscar winner promised a local orphanage a $2 million donation has been denied.

“Our goal is to seek a safe home for the child,” Nguyen Van Trung, director of the Tam Binh Orphan Centre, told Us magazine’s Web site. “Jolie has not promised to give anything to the center.”

Hey, no complaints about the rush job here — we can’t wait to meet the new Jolie-Pitt!

All-Natural Berry

Halle Berry is 40 — but the perennially gorgeous Oscar winner is not exactly showing her age. Which, at least for the cattier among us, begs the question: Has she had, ahem, work done?

“No, I haven’t,” the “Monster’s Ball” star insists to Reader’s Digest. But she hasn’t completely ruled it out: “That’s one thing I’ll never say never about, because I don’t know.”

But as she gets older, Halle says, “I hope I will evolve as a person who realizes it’s really not about my physical appearance and not be drawn to that seductive knife.”

A noble sentiment — but hey, a girl’s gotta keep her options open.

The rift between Tori Spelling and her mother, Candy, was widened by the death of her father, Aaron Spelling — but now the birth of her son may reunite them. Tori gave birth to Liam Aaron McDermott at a Los Angeles hospital yesterday.

‘No soup for you!’; prepare for the ‘Meltdown’. After three weeks of huge DVD sets, this week it’s back to a slew of movies shown during the summer — with “You, Me and Dupree,” “Ice Age — The Meltdown,” “Scoop” and more.

Thanks to the nasty battle brewing between Tori Spelling and her mother, Candy, the planned Aaron Spelling tribute has been canceled.

It’s starting to look like an episode of “Survivor” on “The View.” One day after announcing that she would be leaving the chatfest in July, Star Jones Reynolds got the boot.

It’s no secret that filmmaking in Maryland is big business.
