Poor Ryan Seacrest! The ‘American Idol’ host is not happy that his girlfriend is smooching another man, and now people at CBS Studios have been instructed not to mention the make out scene in the building!

Julianne Hough stripped down to an 80s style purple bikini in Miami Beach yesterday to film kissing scenes with Rock of Ages costar Diego Boneta. The onscreen couple looked like they were having a great time getting into character as they splashed around in the waves, but there was one guy who was not as thrilled about their frolicking — Ryan Seacrest. Julianne’s boyfriend “really doesn’t like her kissing scene”, a source close to Ryan tells us. In fact, he’s so upset about it, people in the CBS building have been told not to bring it up!

“The ‘Dancing with the Stars’ cast and crew were told not to discuss Julianne’s kissing scene in her new movie while in the CBS building,” our insider reveals. “‘Idol’ is filmed there as well, and Ryan often passes by the ‘DWTS’ people. He does not want it addressed and especially in his presence. He would like to pretend his girlfriend isn’t kissing anybody else, even if he understands it is her job.”

Aw! Well it is understandable that Ryan would not want to talk about his (super hot and fit!) girlfriend getting sexy with another man, especially now that the pictures have been released. Plus, as we previously reported, Ryan has been happier than ever with Julianne and even thinks she is “the one”.

Meanwhile, Julianne tweeted her excitement about her first day of filming and her cute brown-haired costar called it “an awesome adventure”.

Hopefully Ryan can stay busy with the American Idol final performance tonight, and just focus on how proud he is that Julianne’s acting career is still going strong now that she’s on her third movie.

The stars of ’90210′ reveal just how far the girls will fall!

The war between Adrianna (Jessica Lowndes) and Silver (Jessica Stroup) has only just begun, and before the third season of 90210 comes to an end, both frenemies will reach their breaking points. Let’s start with Silver, shall we? West Bev’s resident Katie Couric will have a second bipolar flare up this season when Adrianna meddles with her meds, as reported by TVLine — but will it be even bigger than her trash-burning, sex-filming, bottle-throwing escapades in season one? Tristan Wilds has the answer…

“It’ll be bigger because there’s a lot more that she’s doing this year as a senior,” Tristan tells HollywoodLife.com. ”It’ll affect a lot more. You’ve got to watch. It’s going to be great.”

And what about Adrianna? An on-set photo of Jessica Lowndes standing on a ledge hit the web earlier this month, sending shivers down my Adrianna-loving spine. Do we have a potential jumper on our hands?

“[Adrianna] does reach a breaking point that pushes her to a ledge,” confirms Manish Dayal, who plays Ivy’s dying lover Raj.

Unfortunately, Manish couldn’t tell me exactly what drives Adrianna to the brink, so it’s up to all of us to guess. Is it because she hates herself for messing with Silver, or is it possible she’s still ridden with guilt over stealing Javier’s music? Oddly enough, I spoke with the late-great Javier (Diego Boneta) a few months ago, and we joked about the possibility of Javier’s ghost returning to haunt Ade:

“I would absolutely love that,” Diego told me about paying Adrianna a visit from beyond. “Maybe the ghost of Javier is living inside Adrianna.”

What do you think, 90210 fans? Is that idea totally crazy… or just crazy enough to work?
