The good folks at Betty Confidential say that the reason that Kristen Stewart has been even more aggravated and aggressive with the paparazzi this week is because her relationship with Rob Pattinson has hit some hard times.

They are blaming that whole Australian flip-off and airport meltdown on the face that she is having a hard time dealing with her long distance relationship.

“Rob and Kristen’s relationship was going fine,” said the source. “But now that their movie careers have taken off in different directions and different countries. It’s taking a toll on their relationship. It’s not easy to be apart like that and maintain a close relationship. It’s strenuous.”

Says the source, “They only get to talk by phone, and nine out of ten times one of them is interrupted. It’s hard to have a full conversation. Issues get put off – even just small talk gets put off. They can never finish a conversation unless it’s the end of the day and even then they’re too tired to talk.”

“Their last conversation before Kristen headed to Australia was an argument, and she couldn’t get a hold of Rob when she landed in Sydney, so she’s left hanging again. And, when the paparazzi started harassing her and following her, she lost it. She’s never thrilled with the photographers taking her picture, but this time she was really in a bad mood.” Taylor took Kristen out for a jet boat ride on the Sydney Harbour to cool her down, which helped, says the source, But when she saw photographers waiting for her at the dock, she blew up again.”

It sounds plausible. I’ve never doubted that they were in fact a couple. And I also never doubted that they wouldn’t last long after the Twilight films wrap-up. I think everyone forgets they are NOT Edward and Bella and Kristen is only nine-freakin-teen years old. She is a baby. I’m sorry to break it to you Twi-hards…Rob and Kristen will not live happily ever after.

Anyway…she’s probably just pissed off that she is Taylor Lautner are single-handedly promoting Eclipse all over the world while Rob is squared safely away filming Water for Elephants. You know she hates doing press and it’s like he just left her hanging.

Here are some pics of Kristen and Taylor working it in South Korea this week.

Turns out that Lindsay Lohan’s lesbian relationship with Samantha Ronson is not her first. Her jilted ex-Courtenay Semel told a British tabloid how LiLo dumped her for Sam shortly after completing rehab.

“Everyone thinks Samantha is Lindsay’s first lesbian love, but we were very passionate until her fear of being found out drove us apart,” Courtenay told a pal. “At the time she was terrified her career would be over if she revealed her sexual tendencies. But then Samantha came on to the scene and I was dropped.”

Courtenay also dished on how Lindsay slept with countless men to try to convince herself she wasn’t gay before she sank into alcohol and drugs. You can read the entire tell-all article here. Courtenay better watch out. I believe that Sam could deliver a serious ass-kicking if the situation called for it.
