Breakups

That makes sense.

Audrina and the BMX racer broke up earlier this month ... and after the split, Corey went on Twitter and called her a "heartless closed off insecure individual."

But the former "Hills" star hit back in Beverly Hills yesterday -- and then made it clear, she's had her fill of the opposite sex for a while.

We're told the break-up was a pretty mutual decision ... and both parties still "love and respect each other."

The two had been dating since 2007.

UPDATE: The couple's reps released a joint statement confirming the split -- and saying, "The two remain friends and continue to hold the highest level of love and respect for each other."

TMZ broke the story -- Agron broke things off with "I Am Number 4" star Alex Pettyfer because of an artsy photo shoot that surfaced featuring the actor making out with Lydia Hearst and another female model ... even though the pics were taken BEFORE Alex and Dianna began dating.

Now, Lydia tells us ... "I can't help but laugh because it is nothing more than art, and it is beyond ridiculous that anyone would be upset about it.”

Sources close to the ex-couple tell TMZ, "Glee" star Dianna Agron ended the relationship soon after the pictures were released a couple weeks ago ... in which Alex appears barely clothed with models Lydia Hearst and Leven Rambin.

Problem is -- Alex and Dianna started dating last August ... and he shot the pics over a year ago ... back when he was a single man. Dianna's rep wouldn't comment on the story.

It's unclear if he has a six inch or a foot long.

We're told Ryan and Scarlett are living apart. And we're told it's amicable.

Ryan and Scarlett released a statement through their rep, telling TMZ, "After long and careful consideration on both our parts, we've decided to end our marriage. We entered our relationship with love and it's with love and kindness we leave it. While privacy isn't expected, it's certainly appreciated."

Ryan told GQ in September, Scarlett was "the best part" of his life, though he said having a family was "a few years down the road."

Ryan was named PEOPLE magazine's Sexiest Man Alive last month.

Interesting -- the couple was rarely seen out together. The most visible appearance -- at the Tony Awards this past June.

The couple was married in September, 2008.

UPDATE: Ryan Reynolds filed for divorce from Scarlett.

The "High School Musical" star will party at Pure Nightclub in Las Vegas this Saturday.

Don't fret, Vanessa ... 22 really does suck, whether you're with someone or not.

The pair met on the set of "High School Musical" in 2005. They've been together for more than 4 years.

Zac and Vanessa were in Hawaii acting lovey dovey as recently as two weeks ago (below).

In one of the most ridiculous, cry-babyish, pathetic videos to ever hit the web -- Brendon recorded an apology to his former reality TV show girlfriend for sending shots of his wang to some chick he met online ... who then released them into cyberspace.

Brendon claims he was duped by the naked photo recipient -- who allegedly threatened to blackmail the swim coach if he didn't send her video of himself.

Brendon -- who cries more than a 13-year-old girl at a Justin Bieber concert -- claims he wants to spend the "rest of his life" making things right with Rachel.

On a recent episode of "Real Housewives of Beverly Hills," Camille obnoxiously complained that the three bedroom Manhattan apartment she shared with Kelsey (prior to their separation) was too small.

Well, now Kelsey and his young girlfriend, Kayte Walsh, are one-upping Camille by one room and moving on up to a bigger, four bedroom apartment in the sky.
