Justin Bieber put his emotions on display during a performance of Justin Timberlake's "Cry Me A River" at the Boston stop of The Believe Tour. Looks like he's taking his breakup with Selena Gomez pretty hard.

While speaking on the radio, Biebs chatted about his current love life telling the DJ:

"I don't know what's going on in my life. To even assess that it doesn't make sense 'cause I have not made any comment."

Reportedly, Selena is the one who pulled the plug on their romance. Since these two have split several times in the past, we have a feeling they'll be rekindling their young love.

Katy Perry and John Mayer were snapped cruising around Malibu in his black Range Rover on Sunday, and the lovebirds spent their day visiting with several friends.

While Katy seems to have found love with the serial dater, it's being reported that she's still not over her split from ex-husband Russell Brand. After an awkward run-in at the Lakers game the other day, a source tells Heat magazine, "She's not ready to make nice in public. They are friends and talk on the phone now and then - but she still feels majorly let down by him."

But since she's with someone new, don't you think she should move on?

Is it trouble in paradise, is she in between homes or perhaps a mini-staycation for Britney Spears while her new house is prepared?

The X Factor judge, wearing a Junk Food tee and chatting away on her cell phone, hauled several suitcases into an LA hotel over the weekend. With all that luggage, looks like Brit's going to be staying awhile!

As Celeb Digs recently reported, Spears dropped $8.5 million on a Mediterranean-style pad in Thousand Oaks, CA.

The sprawling 8,456 square-foot home boasts 5 bedrooms, 7 bathrooms, an outdoor fireplace, infinity pool, home theater and wine cellar.

As for her hotel stay, let's hope fiance Jason Trawick will be arriving shortly to join his sexy lady. Then again, maybe Brit is looking forward to some alone time.

Miley Cyrus may have been dressed to impress when she lunched at Sweet Salt in Toluca Lake on Saturday, but our photogs on the scene tell us she ended up eating by herself!

Aww! Over the weekend Miley tweeted about her oddball sleep schedule, and she later added, "in need of girlfriends," along with her date of birth, "1123." Maybe she'll meet some new pals at her upcoming birthday party? The starlet turns the big 2-0 on November 23, which is right around the corner! Wonder what she has planned?

In other Miley news, it sounds like her upcoming album will be unlike anything we've ever heard before. In a recent interview with CNN, Miley said, “It’s a really different sound. Not only just for me, but I think it’s something that radio needs right now ... [P]eople don't think [hip-hop and country] make a good hybrid, but actually, so many hip-hop artists are really inspired by country musicians - especially a lot of the artists I've been working with in Atlanta." Can't wait to hear more new tunes!

Ben Affleck and Jennifer Garner took daughters Violet and Seraphina to the Farmers Market in Brentwood on Sunday, and the little ladies both went for pony rides. Even though Violet lost a flip flop, she couldn't stop smiling, and little Sera was so thrilled, she didn't want to get out of the saddle! But eek, where were their helmets?

Later the family was spotted buying produce and sampling some chocolate, and Ben and Jen looked every bit the happily married couple:

On Sunday Katie Holmes and daughter Suri Cruise got ice cream in New York City, and the ladies couldn't stop making silly faces for the cameras ... or for each other!

Katie has been busy with her new Broadway play Dead Accounts, and though it doesn't officially open until November 29, she started preview performances last week. For the next two weeks Katie has Sundays off, but she's taking the stage at least once a day, 6 days a week -- that's quite a busy schedule!
