Jenna Dewan is keeping mum about her recent engagement to Channing Tatum. But she lets her bling do the talking!

The Step Up star headed to Lucky magazine’s Guide to Mastering Any Style party in West Hollywood Thursday night, wearing a slinky black dress and flashing her engagement ring by Neil Lane.

As for her beau’s proposal in Maui last month, “I don’t like to talk about it too much,” Dewan demurred.

Still, she couldn’t contain her enthusiasm. “I’m just so freaking happy,” she gushed to PEOPLE. “It’s great.”

So far, the happy couple hasn’t started planning their big day. “I need to enjoy being engaged,” the 27-year-old explained. “With our schedules, it’s so hard.”
