Tatyana Ali glowed in her first public appearance since announcing her pregnancy and engagement earlier this week.

Showing off her baby bump in a blue Zac Posen gown, Ali stunned at BET's Black Girls Rock event in Newark, New Jersey on Friday night, where she admitted to ET's Sharon Carpenter that she was feeling "a little overwhelmed" since her baby news went public.

"I made that announcement, but I wasn't expecting all of the love that we've received and all of the congratulations," the 37-year-old actress said. "It's been so beautiful. It's made the blessing… even more extravagant and brilliant."

Though she is excited about becoming a mom, Ali did not share the baby's gender or due date, politely explaining that she and her fiancé, Dr. Vaughn Rasberry, wish to keep that information to themselves. She was, however, willing to share that she’s hoping for a "healthy and happy" bundle of joy. "That's what we want," she said.

ET previously revealed that The Fresh Prince of Bel-Air alum met her soon-to-be husband through online dating. "I think it's just a sign of the times," she explained. "That's how people are meeting and talking to each other. I got very lucky!"

The couple hasn't set a date for their wedding yet, but they are in the planning stages. Whenever it is, it's unlikely Ali will unleash an inner bridezilla, as she said that won't go very well with pregnancy.

"Whatever it is, it has to be very calm," she told ET.

That probably rules out a star-studded blowout for the wedding ceremony. "I think we want intimacy," she admitted. "We want to celebrate. It's about love and our family and close friends."

But will her Fresh Prince co-stars be in attendance? "Well, I haven't sent out my invitations, so I haven't got my RSVPs yet," she laughed. "We'll see who says yes!"
