They are inseparable these days!

Paris Hilton and beau River Viperi made Monday their date night when they decided to enjoy a romantic meal at Il Pastaio, and our favorite heiress decided to amp up her outfit with some sexy stockings! We doubt her boy toy minded!

The Simple Life star might be looking to settle down now that she's a year older, but if her 32nd birthday bash was any indication, she's still a party girl at heart! The blonde bombshell hosted an Alice and Wonderland themed fete, and even got Lil' Wayne to put on an impromptu performance.

If these two stay together for the long haul, River better get used to life in the fast lane!

Adrienne Maloof has confirmed that she is leaving The Real Housewives of Beverly Hills.

The reality star tweeted on Monday, "To my loyal fans ... It was time to exit RHOBH. The show served as a wonderful platform, stay tuned!"

Maloof added on her blog, "The show served as a wonderful platform for all the amazing projects that I have in the works. I am forever grateful to my fans, thank you for your support, and stay tuned!"

After getting divorced from husband Paul Nassif on season three of the show (not to mention her famous feuds with co-star Brandi Glanville), Maloof had just about had it with the drama. Maloof was scheduled to tape a reunion special last Friday with Glanville and her other co-stars, including Lisa Vanderpump, Kim Richards, Kyle Richards and Taylor Armstrong, but at the very last minute she bailed.

A source told Us Weekly that Maloof would rather focus on her kids than the show. "She doesn't need that kind of negativity in her life," they told the mag.

Ha! Like these two could ever be low key...

On Monday Kat Von D and fiance Deadmau5 stopped by the Ivy in West Hollywood for lunch, and between her tiger pants and their aggressive groping, our heads are spinning!

We're not sure when the inked up lovebirds will make it down the aisle, but the reality star has certainly made a good impression on his family! Kat tweeted the photo below and wrote, "Dropped off mom-in-law at airport after 2 amazing weeks of having her stay w us. She left behind this gratitude journal for us.. How'd I get so lucky?"

Justin Bieber reportedly showed up two hours late to his concert at London's O2 Arena on Monday, and many of his fans have posted angry tweets about his tardiness and the subsequently shortened set.

According to the official ticketing website for the venue, doors opened at 6:30 (Cody Simpson went on a 7:30, Carly Rae Jepsen went on at 8) and Bieber was set perform at 8:30pm, but a concertgoer told Us Weekly that Biebs didn't even make it to the stage until after 10:30!

When he did arrive, fans were booing, and Us reports that "young fans were falling asleep before he finally arrived," and one fan tweeted, "Lots of unhappy parents on a school night, but feel sorry for little kids crying because they missed half concert. Was good though."

A rep for Justin Bieber had no comment on the matter, but according to Us Mag, a different insider at the show said, "This is not true. He was not supposed to go on until 9:30 and he went on just after 10. He was not two hours late. There was no booing." We can't imagine he'd let his fans down like this, but they can't all be making this up, can they?

UPDATE:
Bieber released the following statement on Twitter:

“since i have been here it hasnt been easy with the press at times but I have loved it. so let me say this … last night i was scheduled after 3 opening acts to go on stage at 935 not 830 but because of some technical issues i got on at 10:10..so…i was 40 min late to stage. there is no excuse for that and I apologize for anyone we upset. However it was great show and Im proud of that ... and tonight we will run on time and look forward to putting on an amazing show for everyone in attendance. my relationship with the media is not always easy but im trying. Im all about the music and the performance and i respect my fans ... now we have a show to do today and Im gonna focus on the positive and put on a great show tonight here in London.”

Marlon Wayans may have said in a recent video clip that Valentine's Day is "for suckas," but after checking out these photos of him making out with a sexy lady in St. Barth (who is NOT his girlfriend of 12 years, Angelica Zackary), he doesn't seem to have any problems with a little romance!

The 40-year-old actor/comedian was snapped living it up on a yacht on Monday, and later in the day he tweeted, "Balling hard in my solitude of peace... Whatever that means." We're not sure what it means either, but based on the size of his yacht and how hot his female companion is, it does seem like he's balling pretty hard!

Not to be mean, but who goes snorkeling with noodles?

Take THAT Justin Bieber! But we're still not sure where all those Girl Scout cookies went, because we don't see an ounce of fat on Selena Gomez's hot body!

On Monday afternoon Selena was snapped strutting around Palmdale in a red one-piece swimsuit and several other sexy outfits, and it's not yet known what exactly she was shooting but she looked amazing!

Selena recently tweeted that she's working on a new album, and aside from shopping, pining for Biebs and munching on a few Thin Mints here and there, she doesn't seem to have much else on her plate. Maybe she's been hitting the gym too? We wouldn't dare slip into something like this without doing a couple hundred crunches a day!

How on Earth does she spend the day sightseeing in sky high heels?!

Kim Kardashian and boyfriend Kanye West exposed themselves to some culture in Paris today, hitting up various museums and acting like normal, everyday tourists.

The pregnant reality star kept warm in a black fur coat, while her beau wore a blue windbreaker. This is "dressed down" for the couple!

Just yesterday, they threw on their finest fashions to attend the Givenchy fashion show, and it appears Kimmy K is favoring more of a masculine style during her pregnancy. Maybe it's because it's easier to cover a baby bump in a blazer than it is in a bustier?

These lovebirds have sure been spending a lot of time in the City of Light!

We're sure mom got coffee and her little one got hot chocolate, though!

Jennifer Garner spent the morning running errands with daughter Seraphina, and their first stop was the Brentwood Country Mart to pick up some morning drinks, followed by a trip to the bank. We love that she doesn't have an assistant doing all these things for her!

The A-list actress bundled up in a grey sweater, jeans, and sneakers, and we couldn't be happier that she's finally figured out running shoes aren't the best look with denim!

Over the weekend, the bubbly brunette hit up the gym and took a Soul Cycle class, and it's clear that after giving birth to baby Samuel in February of last year, Ben Affleck's lady love has been determined to keep off the baby weight.

It looks like running around with her little girl is also giving her a workout!
