The 23-year-old "Vampire Diaries" star posed with her mom, Michaela Constantine, to help launch the "Like Her, Like Me" program which celebrates the power of positive influence and the special moments mothers and daughters share.

"My mom and I are especially close -- we've learned a lot from each other. Growing up, my mom would make us oatmeal with milk; we'd spend time together as a family during breakfast which is, hands down, the most important meal of the day," said Dobrev in a statement. "Through the 'Like Her, Like Me'program, we want to inspire moms and teens to share more special moments and healthy habits -- whether they're swapping stories over a glass of milk or bonding at breakfast."

The mother-daughter duo teamed up with Seventeen to search for three mother-daughter pairs who embody the program's mission of what it is to be good role models for one another. The winning pair will get to create their own "got milk?" ad that will be featured in the magazine in the fall.
