Hilary Duff is set to tie the knot with her hockey player fiance Mike Comrie at the exclusive San Ysidro Ranch in Santa Barbara.

Although there are conflicting reports on whether or not it will happen this weekend, Hilary chose the romantic spot where John F. Kennedy honeymooned with Jackie O. because of “its sense of Old Hollywood glamour and romantic style,” an insider tells In Touch. Calls to her publicist were not immediately returned.

Hilary, who's been working out like crazy in the weeks heading up to her wedding, has been engaged for just six months.

Step Up star Channing Tatum ducked out of his West Hollywood gym last night after his daily workout. Now this dude knows how to stay buff! Who else wants to get a look at his Situation???

Kelsey Grammer is expecting his fifth child with new girlfriend Kayte Walsh, a British flight attendant who is 26 years his junior, according to a new report.

Kelsey filed for divorce from his wife of 13 years, Camille, just six weeks ago.

Although Kelsey had previously denied reports that he was spotted kissing another blonde, saying it was his eldest daughter, Spencer, there's no denying that Kayte looks as if she could pass for his daughter!

And Kelsey's not just old enough to be her dad -- he's older than Kayte's dad! But her father, soccer coach Alan Walsh, doesn't seem to mind the age difference.

"It’s great news and we are very pleased for them both," he told the Daily Mail. "I don’t know how long they have been together and I have not met him yet, but I’m looking forward to it. We just found out about her pregnancy a couple of days ago."

As for how they met, the coach says, "I think they met in New York socially because she works for Virgin Airways and often stops over in America. The main thing is for them both to be happy and they are – they have just hit it off together."

No word on exactly when they met but if she really is pregnant, her telltale bump should give things away soon enough!

Calls to Kelsey's rep were not immediately returned.

Dina Lohan will be giving her first sit-down interview to Matt Lauer on the Today Show.

Lindsay's mom plans to talk about Lilo's drama with the law, her time behind bars and how she's holding up in rehab.

So far Dina has only commented that her daughter is "in good hands" while at UCLA Medical Center for her 90-day rehab sentence. Mrs. Lohan has also said, "Lindsay is with the utmost professionals."

The exclusive Today Show interview is set to take place tomorrow morning. No word on whether Ali will be joining her mom in New York for the taping.

We'll be watching!

Angelina Jolie is defending her daughter Shiloh's decision to chop off her locks and dress like a boy, saying "I think it's beautiful."

Jolie also explains that while she has no problem with the way Shiloh, 4, is expressing herself through her appearance, it's not exactly her choice.

"It's not my choice," Angelina told Stylist magazine. "I have a very strong willed four-year-old girl who tells me what she wants to wear and I let her be who she is." Jolie continued, "I think children should wear what they want and express themselves, so we give them different options of things."

As for how Shiloh convinced mom to cut her hair? "Shiloh cried and said, 'Please cut my hair off, I don't want to have long hair.'" Jolie said. I'm not going to leave it long because somebody thinks I should. I want to do what's in her head and what's in her heart is to dress like that. I think it's beautiful."

Jolie also defends her relationship with Brad Pitt, which many speculate started on the set of Mr. and Mrs. Smith.

"It didn't begin on the film set," she says. "We became friends on the film set, but [the relationship] began after."

However, that statement contradicts an earlier one in which she said of the idea of her children watching the film, "Not a lot of people get to see a movie where their parents fell in love."

As Jennifer Aniston would say, uncool Angelina!

His name is Howard Bragman, and authorities want to question him. Why?

The celebrity publicist was briefly hired by Oksana Grigorieva (he reportedly dropepd her before officially signing on) and sources tell The Hollywood Reporter that investigators want to know if she paid him using funds from the sale of those nasty audio recordings...

LA County Sheriff's Department spokesman Steve Whitmore declined to comment - as did Bragman himself - but the sheriff's department has confirmed its investigation of Grigorieva's abuse allegations, as well as whether or not she used the audio recordings to get money from ex Mel Gibson.

Authorities also want to know if Bragman knows anything about Gibson's alleged abuse of his babymama and/or their baby.

So much drama for Mel and company!

Deryck Whibley, Avril Lavigne's ex hubby, won't be hitting the stage anytime soon due to a back injury he sustained after being attacked in a Japanese bar.

Sum 41 has decided to pull out of the Vans Warped tour while their 30-year-old lead singer recovers.

The following statement was released on the band's website:

"Knowing that they are unable to deliver their signature high energy show, Sum 41 made the tough decision that a break is needed while Deryck begins rehabilitation for the slipped disc. He is expected to make a full recovery with the necessary treatment and rest."

Whibley was attacked by three men in a bar after performing at the Summer Sonic rock festival in Japan. Sum 41 hopes to resume their European tour by the end of this month.

Lavigne, who's currently dating Brody Jenner, split from Whibley back in September 2009.
