knows a thing or two about keeping a relationship in tact.
Despite splitting temporarily
from beau Scott Speer
in December, Tisdale, 26, and the music video director, 30, are currently going strong.
"Communication is so key," Tisdale told PEOPLE at Mixology 101 inside L.A.'s Farmer's Market Monday, when asked how she makes her relationship work. "Especially in this business, I'm always traveling and doing something else. So I think communication is the foundation of it all."
Tisdale – who was celebrating the Sole Society-sponsored premiere of Bravo's Miss Advised
, a show she co-executive produced – gushed that she was "super stoked" to have Speer on hand lending his support at the event.
"Scott hasn't seen [the show] yet," she said. "He'll see it [tonight] when everyone else sees it."
Although Tisdale isn't actually on the show, she can certainly relate to the three dating advice professionals – Emily Morse, Amy Laurent and Julia Allison – who star on the hour-long series.
"I give dating advice on a regular basis," she says. "It's not that I'm any expert, but it's always nice to share that with your friends."
As for her most followed piece of self-recommended guidance, Tisdale says, "I'm very old fashioned when it comes to dating, so I definitely wait for the guy to text me or call me."
