Taylor Swift and Harry Styles (Tom Meinelt/Splash News)Is Taylor Swift is ready to share her latest romance with the world?

After being spotted holding hands on the set of "The X Factor" last month, the 22-year-old "Red" singer and One Direction's Harry Styles, 18, were photographed together for the first time on Sunday. Looking cozy and comfortable with one another, the young Hollywood stars strolled through Manhattan's Central Park with friends. While there, they visited the Central Park Zoo — and Swift was appropriately dressed for the animal-friendly afternoon, wearing a sweater with a fox on it.

Despite having been with the same man, Carl Dean, since the couple first met back in 1964 at a laundromat, Parton's husband is almost never spotted in public. The singer/actress has previously said he simply stays out of the spotlight, and in a recent interview with Reuters, jokes about the fact that some fans have doubts there even is a Carl Dean.

"They don't think he really exists!" exclaims Parton, 66. "When I was doing my show, we were thinking about having a different guy knock on the door every night, as my husband, and then one night he would be a midget, and one night he would be a black man, and one night he would be like a boxer or a wrestler, all these different things that people imagine what my husband looks like."

With Ashton Kutcher and Mila Kunis' relationship heating up (they spent Thanksgiving together in Italy), people have been feeling a little sorry for Demi Moore, who hasn't appeared to have rebounded as easily from her breakup with Kutcher a year ago. But don't worry about the 50-year-old actress — she seems to be doing just fine.

According to a report in the New York Post's Page Six, Moore has been quietly dating a man nearly half her age — and eight years younger than her soon-to-be ex-husband, Kutcher! The new guy in her life is said to be Vito Schnabel, the 26-year-old son of director Julian Schnabel. Vito is a New York City-based art dealer and curator, who is often in Miami and London for work.

When Moore traveled to India earlier this month to attend the birthday party of Naomi Campbell's billionaire boyfriend Vladimir Doronin, Vito was by her side and they were reportedly "dancing and grinding all over each other," says Page Six.

Gavin Rossdale definitely has some explaining to do. On Sunday, while wife Gwen Stefani was busy performing with No Doubt at the Gibson Amphitheatre in Los Angeles, the Bush rocker went on a hike with their two sons, Kingston and Zuma … and their nanny, a dead ringer for a 20-years-younger Stefani. That wouldn't be so strange since the blond nanny is always with the family, but it was the way-too-intimate contact between Rossdale and the young woman that has raised a few eyebrows.

Angelina Jolie and Brad Pitt (Getty Images)At long last, wedding bells for Brangelina!

Since Brad Pitt popped the question to Angelina Jolie last April, the couple has remained vague about their wedding plans, prompting some to wonder if their engagement will last as long as their seven-year courtship. However, in a new interview the 48-year-old actor, who has six children with Jolie, hints that the big day is imminent.

Kate Walsh may not be the best cook in Hollywood, but fortunately her friend is. The "Private Practice" star's good pal Tess Rafferty just published a book, Recipes for Disaster, about learning to cook and the dinner parties she has thrown over the years. Since Walsh is admittedly not very comfortable in the kitchen, she turned to Rafferty, who whipped up coq au vin (chicken with wine) — her own take on a Julia Child classic — for the taping of this "Sunday Dinner With…" episode. "I still call my mom to ask her how to cook a chicken," jokes Walsh. Watch as the actress serves up stories about her worst auditions, playing the drums, and what inspired her fragrance, Boyfriend.

Their statement, released by the "Amistad" actor's rep, makes it clear that the two never married. Although Simmons, 37, and Hounsou, 48, exchanged vows in West Africa in summer 2008, they never filed for a marriage license in the U.S. because at the time she was still wed to Russell Simmons.

Mayim and Michael. (Gregg DeGuire/WireImage)All that attachment parenting may be beneficial for Mayim Bialik's two kids, but it doesn't seem to have helped her marriage. On Wednesday, it was announced that "The Big Bang Theory" actress split from her husband of nine years, Michael Stone, citing "irreconcilable differences." On the Jewish parenting website Kveller.com, the 36-year-old was adamant that her style of parenting — her sons Miles, 7, and Fred, 4, sleep in the same bed as she and Stone — played no part in the split. "Relationships are complicated no matter what style of parenting you choose," wrote Bialik.
