Many actresses have portrayed mothers on the big screen, but some of them have managed to do so with decidedly more sex appeal than others.

Most of the actresses discussed here are known for their roles as mothers both on and off screen, although one winner has never accepted this role in real life.

Some of these movie moms have made us laugh, while others have made us cry, but what these hot mommas have in common is an undeniable sex appeal and boatloads of talent (three Oscar winners made the list).

Certainly dozens of actresses potentially deserve a spot on this list, but if we have to limit our choices to just five, to us, these are the hottest movie moms of all time ...

Jane Seymour in Wedding Crashers

No. 5: Jane Seymour - "Wedding Crashers" (2005)

Who can forget Kathleen "Kat" Cleary's (Jane Seymour) aggressive, don't-take-no-for-an-answer come-on to Owen Wilson's character in 2005's "Wedding Crashers"?

In this sure-to-become-classic comedy film, Seymour plays a wealthy wife and mother of three who attempts to seduce a guest at her daughter's wedding. To more mature generations of fans, Seymour may be better known as "Dr. Quinn, Medicine Woman."

In real life, this two-time Golden Globe winner has been married four times and is the mother of four children. She also has stepchildren through her marriages to David Flynn and James Keach.

Although not as famous with the Facebook generation as some of our other winners, there is no question that Seymour is one hot momma, both on and off screen.

Jennifer Coolidge, Stifler's mom in American Pie

No. 4: Jennifer Coolidge - "American Pie" (1999)

Jennifer Coolidge may not be a household name, but nearly every American knows who Stiffler's mom is.

Coolidge is best-known for seducing her teenage son's friend in the "American Pie" films, voicing the unforgettable line, "I like my scotch and men the same way: aged 18 years."

An accomplished actress, Coolidge has since starred in "Legally Blonde" and has become a favorite of director Christopher Guest, appearing in "Best in Show" (2004) and "For Your Consideration" (2006).

In real life, Coolidge had been in longtime relationship writer/producer Banks McClintock, but the couple reportedly split in 2010. She has never tried out the role of motherhood off screen. Coolidge may not be listed in the "Hot 100" like some of our other movie moms, but she'll forever be known as Stiffler's sexy mom.

Julia Roberts in Erin Brockovich

No. 3: Julia Roberts - "Erin Brockovich" (2000)

In "Pretty Woman," Julia Roberts proved that she knew how to play sexy, and she's played a mom on more than one occasion, but in 2000, she combined these talents to play a real life sexy single mom as the title role in "Erin Brockovich."

Roberts won an Oscar for this role, cementing the fact that she brings more to the table than long legs and a gorgeous grin.

Arguably the best-known actress in Hollywood, Roberts has tied with our upcoming choice for hot movie mom No. 1 for the most appearances on People's "50 Most Beautiful People" list.

In real life, Roberts is married to cameraman Daniel Moder and took some time off from acting when she gave birth to twins in 2005.

Angelina Jolie in Beowulf

No. 2: Angelina Jolie - "Beowulf" (2007)

Daughter of Academy Award-winning actor Jon Voigt, Angelina Jolie's personal life often overshadows her acting career, although she took home an Oscar in 2000 for her performance in "Girl, Interrupted."
