My longtime agents Mark and Jack held a wonderful 50th birthday party for me last year. It was a great way to celebrate this wonderful milestone: I'd reached the half-century mark (!) and I was thrilled to celebrate with family and friends. My old One Day at a Time cast mates, Pat Harrington and Mackenzie Phillips, celebrated beside my new Hot in Cleveland team, Jane Leeves and Wendie Malick. Plus, it was at this party that Tom and I announced our engagement! What a difference a year makes!
