The actress, who became engaged to businessman Tom Vitale last March, isn't rushing down the aisle because she's too busy enjoying her pre-honeymoons.
"One of these days we're going to get married, but we just had an amazing three weeks in Italy, and so now we're planning our second honeymoon for us to actually get married and go again," Bertinelli, 50, told PEOPLE at Thursday's 19th Annual BAFTA Los Angeles Britannia Awards. "We're doing all the honeymoons first."
So far she's revealed the wedding will be small, with likely just the two of them and a witness in attendance, and she says she'll wear black rather than the traditional white gown.
One detail she won't have worry about: fitting into that dress, whatever color it is.
The Hot in Cleveland actress, who famously lost weight on the Jenny Craig diet, says, "I'm not stopping" the program.
"Life just feels easier," she says about managing her weight. "Life just feels not as stressful when I don't have to worry about what I'm putting on in the morning. I know it sounds trite, but to a lot of us women it really does mean a lot when you start the day – you put a pair of jeans on and they don't make you feel like crap."
