Parade.com, the online presence of Parade Magazine, takes advantage of these long, hot months to post pop culture polls, and recently scooped up some fairly interesting dirt about the way theater-goers view their favorite film stars. Some of the most interesting findings:

 - New mom Nicole Richie has the most-improved reputation (43%), according to respondents. Mel Gibson came in second with 22%, Tom Cruise is next with 21%, followed by perennial bad girls Britney Spears (9%) and Paris Hilton (3%). Despite multiple bouts in rehab, Lindsay Lohan came in last (2%), indicating most people think she still can't get her act together.

- Sometimes it may feel like celebrities and boldfaced names change love interests as often as they change their socks, but respondents think First Daughter Jenna Bush and new hubby Harry Hager are most likely to succeed as a couple (80%). Newlyweds Mariah Carey and Nick Cannon and Ashlee Simpson and Pete Wentz each came in last with 2%.

 - Hollywood's most unlikely couple is Jennifer Aniston and John Mayer (50%), followed by Heidi Klum and Seal (18%), Ashton Kutcher and Demi Moore (17%), and Ashlee Simpson and Pete Wentz (11%).

 - The hottest new mama is Halle Berry (42%), followed by Jessica Alba (17%), Christina Aguilera (14%), Jennifer Lopez (13%), and Salma Hayek (12%).

 - The favorite celebrity dad is Will Smith (37%), followed by Brad Pitt (23%), Ben Affleck (17%), and Matt Damon (16%).

 - Ironman (played by Robert Downey Jr.) and Spiderman (played by Tobey Maguire) tied with 35% each for best modern-day superhero, followed by Christian Bale as Batman (13%) and Ed Norton as The Incredible Hulk (9%).

 - Among the beautiful people, the best-looking male celeb is Brad Pitt, with 34% of the vote. Other hotties include: Matthew McConaughey (28%), Jake Gyllenhaal (13%), and Will Smith (13%). Angelina Jolie tops the list of best-looking females, with 35%. Not far behind are Jennifer Aniston (24%) and Beyonce (16%).

 - The most-likely-to-succeed award goes to Miley Cyrus (29%), over a three-way tie among Shia LeBouf, Juno star Ellen Page, and Rihanna, all with 17%.

 - Not surprising, the cutest couple is Will and Jada Pinkett Smith, followed by Reese Witherspoon and Jake Gyllenhaal (30%), and Tom Cruise and Katie Holmes (12%).

The poll was conducted on Parade.com among nearly 4,000 Americans. The results of the entire poll are posted on Parade.com.
