Jenny McCarthy and Charlie Sheen?

Dec. 16, 2010— -- The Hollywood dating scene got a lot more interesting this week, with newly- single stars Ryan Reynolds, Scarlett Johansson, Liz Hurley, Michael C. Hall, Zac Efron and Vanessa Hudgens back on the block.

"I can't wait to see who Ryan Reynolds dates next," Jenny McCarthy gushed on "The View" Wednesday.

Nor can we, which is why we thought it would be fun to make some suggestions to Reynolds and other single celebrities, about who they should date in the coming year. We enlisted the help of Match.com's relationship expert, Whitney Casey, author of "The Man Plan: Drive Men Wild -- Not Away."

Casey's advice to all celebrities and us mere mortals: "Be cognizant about the time they spend making moments together. Once you become one with someone else, you can't continue being that celebrity you were."

Casey believes Reynolds and Johansson, who announced Tuesday that they were ending their two-year marriage, fell victim to spending more time apart than together, "sharing memories rather than making memories." She said a good rule of thumb for all couples is: 30 percent of the time should be spent pursuing individual goals, friends and work and 70 percent should be spent together.

"Here we can use Brad (Pitt) and Angelina (Jolie) for something good," she said. "They are way busier, yet they manage to keep a healthy relationship. They set apart their schedules to be together or they shoot in the same locations."

If two of the biggest stars on the planet can make it work, then there's hope for other star couples. Here are our suggestions for potential matchups in 2011:
