90210 royalty!

Costars Jessica Lowndes and Matt Lanter shared a new photo on Twitter from an "old school" photo shoot they shot this week.

"Working with the lovely Ian Derry & Matt Lanter channeling Queen Elizabeth before the blue rinse!" Lowndes, 23, tweeted Wednesday with the photo. 

Lanter, 29, posted the same one, writing, "#oldschool photoshoot with Jessica lowness with mr Ian Derry behind the camera at The Dorchester London, England."

The 90210 stars recreated an old photo of Queen Elizabeth and Prince Philip, Duke of Edinburgh at the luxurious Dorchester hotel in London, England. And in case fans couldn't tell which was which, Lanter explained, "Original on the bottom, recreation on top."

And Lowndes and Lanter should be partying like royals right now! CW announced on Thursday that 90210 will be picked up for a fifth season this fall.

"It's official! We are back for season 5! Thanks CW Network," Lanter tweeted Thursday. "Can't wait to get back to the zip code and keep making more for u guys!"
