6. Julianne Hough And Ryan Seacrest

Long-term potential: It takes a special lady to keep up with Seacrest, affectionately dubbed "The Hardest-Working Man in Hollywood." (His most recent resume builder: He served as an NBC Olympics commentator this past summer.)

The DWS alum's acting career is also heating up: She's currently filming Safe Haven, a romantic drama by Nicholas Sparks. "We work hard, and it's why we're attracted to each other," Hugh explained at a Samsung Galaxy Note II launch party.

The couple psyched us out during an American Idol episode that aired in May. Seacrest told Hugh he had to ask her a serious question. He reached into his suit jacket to pull out a...piece of note paper. ""Will you…give this note I wrote to [Rock of Ages costar] Tom Cruise? I'm such a big fan -- I loved him in Cocktail," he said.

When he pops the question again (for real), don't expect him to televise the wedding-he told Life & Style that's a no-go. less
