What a surprise!

Demi Lovato recently made an unexpected admission during a WBLI radio interview when she revealed she has an older half-sister she never knew existed until this year!

"I have an older sister I've never known my whole life, who's in her 30's. She's my half-sister, but I talked to her for the very first time in my life around when I turned 20," she confessed.

The "Heart Attack" singer didn't offer any other details like the sister's name or whether she's her father's or mother's child, but she did explain how their first meeting went down.

"I asked her, I said, 'Why haven't you ever contacted me?' She said, 'Well, I never wanted you to think I wanted anything from you. So I've just been kind of waiting to see if you wanted a relationship," she divulged.

The X-Factor judge was taken aback with her sister's sincerity, too!

"I thought that was so incredible. So, I actually have three sisters," she added.

Lindsay Lohan should take a page from Miss Lovato's book!

Talk about letting the cat out of the bag!

Jessica Simpson accidentally confirmed she was expecting a baby boy during an appearance on Jimmy Kimmel Live last night, and she couldn't have done it in a more typical fashion!

The blonde bombshell was chatting with the talk show host about her second pregnancy and how she has experienced bad morning sickness this time around when she accidentally revealed the gender of her unborn child.

"The crazy thing is I never knew a weiner could make me nauseous," she joked before adding, "Well, I guess I just told the world that I'm having a boy!"

Her little man, rumored to be named Ace, will join 10-month-old sister Maxwell. The fashion mogul might have expanded her family at a rapid rate, but she has a plan to pause the baby making long enough to make it down the aisle with fiance Eric Johnson!

"Maybe I should go back to when I was younger. I was a virgin before I married [to Nick Lachey], so maybe I should just completely reverse and just stop having sex all together until Eric and I actually say 'I do'," she kidded.

That's probably a good idea!

Except there was one problem -- his car was left totally unattended!

Chris Brown stopped by Emerson in Hollywood last night, and rather than valet parking his red Dodge Viper, he decided to stop right in the middle of La Brea Blvd and park it there. When cops went to reprimand him for blocking traffic, they couldn't find him, but luckily one of his pals smoothed things out with the police and Chris came out of the club shortly thereafter, around 2:15am. Chris didn't get ticketed, but cops were finally able to exchange a few words with him.

Check out the video below:

Is she trying to tell us something?

Miley Cyrus squeezed in a late night recording session yesterday, and it seems the Hannah Montana star is trying to send a message without saying a word because she wasn't wearing her gold engagement ring from Liam Hemsworth!

Her Hunger Games actor beau has been accused of cheating on his fiance with Mad Men actress January Jones at a pre-Oscar party, and rumor has it that the couple are headed for splitsville if they haven't already called it quits!

Hmm, not sure if this is real or faux, but at first glance we thought Jessica Simpson was snuggling up to a Chow Chow in the back seat of her SUV on Wednesday night!

The pregnant singer/actress was snapped leaving Jimmy Kimmel Live! in Los Angeles, and she's been making the rounds to promote the upcoming second season of Fashion Star, which premieres on March 8.

Jessica sat down with Ellen DeGeneres on Wednesday and after a quick chat about the show, she chatted about what everyone really cares about ... her second pregnancy! Jess joked, "Apparently protection was just thrown out the window," and prior to that she chatted with Ryan Seacrest on KIIS-FM and when asked about her unplanned pregnancies, she said, "I think originally I had wanted three [kids] and now that I have one and another one on the way, I feel like I could stop here. It's a lot of work. Obviously it pays off and it's totally worth it, but it's a lot of responsibility." Jess then added, "Accidents do happen!"

How adorable are these two?!

On Wednesday night Jessica Alba and her oldest daughter Honor arrived back in Los Angeles after taking in Paris Fashion Week, and it looks like both of the ladies had a blast on their trip!

While Jess spent plenty of time sitting front row at fashion shows like Stella McCartney, Kenzo and Valentino, she also took her little girl to the Jardin d'Acclimatation amusement park in France, where they rode on roller coasters and took a spin on the carousel. Sounds like the perfect European getaway to us, but we're guessing hubby Cash Warren and little Haven are happy to have them back!

We can't believe how big little miss Matilda is getting -- it seems like just yesterday she was a toddler!

On Wednesday Michelle Williams took her beautiful daughter shopping at CrewCuts in New York City, and it looks like the 7-year-old already has quite a sense of style! Her late father Heath Ledger would definitely get a kick out of her quirky clothes...

In other news, Michelle currently appears on the cover of AnOther magazine, and she revealed that when she is filming she only has room in her life for two things. Michelle said, "I guess realizing that there is no such thing as a perfect balance, it’s not like riding a bicycle, you don’t want to just figure it out and stay on track. I find that when I’m working, there are only two things: there’s my work and the kid, everything else has to fall away."

Guess that would explain why things didn't work out that well with Jason Segel...

After going shopping at Rag and Bone and grabbing a bite to eat at Urth Caffe in West Hollywood, we spotted a pregnant Jenna Dewan-Tatum dropping off her mother at Los Angeles International Airport on Wednesday afternoon. Jenna gave her a huge smooch before sending her on her way, and we also got a peek at her make-up-free face. Kinda amazing how great she looks au naturel!

So what's next for the mom-to-be? At the Oscars last month Jenna's hubby Channing told Ryan Seacrest that she will be giving birth in London while he shoots his next film, and they're going to wait until then to find out the gender of the baby. Talk about adventures and surprises!
