On Friday morning Sienna Miller and her darling daughter Marlowe went for a stroll in New York City, and later we spotted the starlet and her slightly younger baby daddy Tom Sturridge out for a walk.

It seems to us like motherhood has totally mellowed the 31-year-old actress, doesn't it? She's notorious for being a sourpuss with photographers, so it's nice to see her with a pleasant expression on her pretty face!

We have to applaud him for speaking so openly about his struggles!

Matthew Perry is healthy and sober these days, but for a long time the Friends star battled drug and alcohol addiction in private, and now he's telling his story in hopes of helping others!

In a new interview with ABC News, the actor details how he hid his problems from his co-stars and close friends and family.

"Mostly it was drinking, you know, and opiates. I think I was pretty good at hiding it, but, you know, eventually people were aware," he confessed.

He completed a 1997 rehab stint for a Vicodin addiction only to go back to rehab in 2001 for similar issues, but the Fools Rush In star eventually kicked his problems for good. In fact, being a famous TV star made falling off the wagon virtually impossible.

"I couldn't just walk into a bar. Everybody in the bar would go, 'You, you can't do that. I just read that you can't do that. You can't. You can't,'" he added.

Going through the steps of recovery motivated the funny man to open the doors of his Malibu home and help others beat the disease.

"If you're thrown from treatment to the outside world, sometimes it's too bumpy," he explained of his decision to operate a sober living facility from his residence.

Bravo Matthew!

Scott Disick sure loves his Starbucks.

The reality star grabbed iced tea in Calabasas yesterday from his oft frequented coffee house ... in a yellow Ferrari -- you know, everyone's go-to car for a tea run.

Scott looked stern during the outing, donning a plain, black T-shirt, faded jeans, and leopard print loafers. He was first spotted with his new ride a few days ago while jewelery shopping in Calabasas. The father of two probably doesn't allow his kids Mason and Penelope near his new baby.

We're guessing the car was a birthday present for his big 30, which he celebrated in style with girlfriend Kourtney Kardashian in Las Vegas last Sunday. We wouldn't expect anything less from a lord.

We'll get to see more of the over-the-top star when Keeping Up with the Kardashians season eight premiers on Sunday. He also stars in the E! Online web series Lifestyles of a Lord.

After jetting around the world for a few promotional appearances, Selena Gomez is back in Los Angeles!

On Thursday the 20-year-old starlet co-hosted NewMusicLive in Toronto, and prior to that she was in New York City. Looks like she just missed her on-again/off-again beau Justin Bieber! Maybe when he comes back to Los Angeles they'll reunite again?

Biebs (and his friends!) may be getting into trouble with the law, and he doesn't have another tour date until late June, so maybe Selena can set him straight during his time off?

Her Twitter wars are neverending lately!

Amanda Bynes is absolutely furious at Lance Bass over recent comments he made about her during a Las Vegas radio interview, and the troubled starlet had some choice words for the ex-boybander when she lashed out via Twitter.

The N'Sync singer was questioned by the radio DJ about his onetime pal and her erratic behavior, and he gave as honest of an answer as possible. "It's one of those situations where obviously there's some mental problems there and she's not able to see that," he explained on-air.

The former Nickelodeon star was none too pleased with his take on things!

"I ignored Lance Bass on Twitter and now he is saying I have a mental illness. Sorry you're an ugly ex boy band member with no talent or career," she posted on her Twitter.

"I haven't spoken to Lance Bass in 11 years. To say I have a mental illness out of nowhere makes me lash out! You're making me crazy!" she added.

Mr. Bass was shocked by her outburst and feels her reaction was an indication she needs professional help.

"The Amanda I know would never have said something like this to me. Either this is a fake person or she really does have a mental illness. Way too sad. I reached out - all I can do," he posted in response.

Add Lance to list of celebs on Miss Bynes' bad side!

Robert Rodriguez's exploitation film Machete Kills stars everyone and their (hot) mom.

The movie trailer was released yesterday and features Sofia Vergara shooting bullets out of her heavy duty bra, Lady Gaga prancing around in fur with a gun hidden behind her back, and beauty queen Amber Heard kicking butt.

Jessica Alba and an eye patched Michelle Rodriguez return for the Machete squeal, while Charlie Sheen -- ahem, ahem Carlos Estevez -- plays the new gun-wielding U.S. president who saves Danny Trejo's character of Machete from being executed in order to kill Mel Gibson's missile-launching billionaire villain.

You can watch all the stars, as well as Antonio Banderas, Cuba Gooding Jr., and Vanessa Hudgens, get bloody on the big screen on September 13.

Make sure to watch the very end of the video to catch a hip-thrusting, midriff-flashing Sofia.

Kendall Jenner strikes a pose for Agua Bendita swimwear's new campaign, and she looks absolutely flawless in this ruffled floral bikini.

Kendall recently revealed that she wants to become a Victoria's Secret model, and seeing as VS Angel Candice Swanepoel is the other major face of the new ad campaign, it seems like she's not that far off! Kendall told E! News, "It's always been kind of a dream of mine. It's something I'd love to do." Do you think VS would ever hire the reality starlet? We totally think they should!

And not only does she look great in a swimsuit, but she's totally got killer street style too! Her outfit yesterday was so very Nicky Hilton-esque, and we love it:

Philip Seymour Hoffman has completed 10 days in rehab for snorting heroin.

The Oscar winner told TMZ that he had been clean for 23 years, and added that he began with prescription pills and recently graduated to heroin. Hoffman credits "a great group of friends and family" for assistance in getting the necessary help he required.

In 2006, Hoffman opened up about his prior substance-abuse issues on 60 Minutes, which began shortly after he graduated from New York University. "It was anything I could get my hands on ... I liked it all," he said. "I went [to rehab], I got sober when I was 22 years old. You get panicked... and I got panicked for my life. It really was just that."

The 45-year-old actor is reportedly back at work, shooting his next film project in Europe.
