Terminally Blonde(2005)

Nicole Sheridan is not your ordinary mom. Her daughter Katie Morgan is reminded of this when she comes home to find Nicole with a hot stud in the middle of the afternoon. Embarrassed by her mom's lustful behavior, Katie rushes off with her boyfriend for some privacy and sanity. Katie's friends don't see why Katie's embarrassed; they find her mom a wealth of sexual wisdom and relationship advice. It's not until Katie decides to be a bit more sexually open-minded herself that she realizes how much her mom really means to her.
