"We want to do it sooner rather than later," Sadowski told Usmagazine.com Wednesday at the PinkIsTheNewBlog launch party at Hollywood's S Bar. "But my parents want me to finish school first and that won't be until 2010. So we want to do it probably a little bit before graduation, but I need my parents' help to plan the wedding!"
Added Wahler (who used to date Lauren Conrad): "And if her parents don't agree, it's a no-go! So we are looking, realistically, at 12 to 15 months from now.
(See more celeb wedding photos.)
Wahler is pitching around a new reality show -- rapper Warren G has signed on -- and said the wedding "will be a part, but it's not going to be the focus of the show."
The two have gotten into marriage gear by moving in together.
"It's going well," Wahler said. "We have my assistant/best friend there too. It's kind of awkward, but what the hell!"
"It's like You, Me and Dupree!" she told Us. "Sometimes it can be a little too much!"
At least they aren't sharing space with Spencer Pratt and Heidi Montag.

Asked about the pair, Wahler laughed and said to his publicist, "I’m being very careful."
He added, "I wish them the best of luck. Seriously, they’re just not my type of people, so, I mean, I don’t follow them, I don’t care about them.
"They do their own thing," he added, "and I do my own thing."
