See Diane Keaton tomorrow

When Diane Keaton speaks at tomorrow's Simmons College of Management leadership conference, don't expect her to focus only on her acting career. The Oscar-winning "Annie Hall" star should also have plenty to say about the fact that she's become a real estate maven.

For the last few years, Keaton has bought houses around Los Angeles, renovated them into masterpieces, and sold them for big money. During a recent phone interview, Keaton told us she doesn't like to refer to her buy-fix-and-sell routine as house flipping. She loves these homes enough to live in them -- and she does. "I'm sure this is a detriment to my two children," she joked, about the constant moving around. "I fix them ... then I live in them. I want to enjoy every minute of living in them. Then I think, if this is an opportunity to make money ..."

Keaton sold one of these special homes to Madonna for $6.5 million. Another recent property, a Spanish colonial, went on the market for more than $12 million. Keaton says she's highly aware of the depressed housing market but that it hasn't stopped her. There are deals to be had, she told us. Good to know.

Keaton also disclosed that she has a soft spot for her own movie "Baby Boom." The 1987 film had Keaton portraying a career woman who's forced to reprioritize after inheriting a baby. Keaton said the film's message is important for women in business. She only wishes "Baby Boom" had done better at the box office. "It was disappointing because it wasn’t a big hit," she said. "It opened against 'Three Men and a Baby,' which was a big hit." The glass ceiling strikes again.

Keaton's next acting project is a "Morning Glory" with Harrison Ford and Keaton's "Family Stone" co-star, Rachel McAdams.

The Simmons College "Vision to Voice: Leadership in the Global Age" conference is tomorrow. Other speakers include journalist Charlayne Hunter-Gault, Build-A-Bear Workshop Chief Executive Maxine Clark, and former U.S. Surgeon General Antonia Novello, M.D. You can get tickets here.
