Brooke is busy getting ready for her baby with her fiance and Baywatch alum David Charvet. Brooke says she’s not feeling very glamorous at this stage in her pregnancy.

“I’m getting ready to have my baby, so I can’t go anywhere, I can’t do anything,” Burke told PEOPLE at the Los Angeles Ballet’s debut of The Nutcracker in Beverly Hills on Saturday. “I’m just kind of waiting it out – not strictly at home, (but) no skiing and no vacations this year. Just waiting for baby.”

“I’m just trying to maintain my lifestyle, and to stay healthy and exercise and kind of embrace the time,” Burke says.

Burke, 35, and Charvet, 34, announced their engagement and pregnancy in August. Burke has two daughters, Neriah and Sierra, with plastic surgeon Garth Fisher, from whom she split in 2005.

As for wedding planning, that’s going slowly, for now. “We’re just going to wait for the baby and not stress ourselves out planning the wedding. Then try to do it as soon as possible,” Burke says.
