PARK CITY, Utah (Reuters) – Christie Brinkley ended 2008 with an ugly public divorce from her unfaithful fourth husband, but the former supermodel says she is full of optimism for 2009, sparked by U.S. President-elect Barack Obama.

Brinkley, who was at the Sundance Film Festival to launch her third "got milk?" advertising campaign, said she would be glued to the television on Tuesday to watch Obama be sworn in as the first black U.S. president.

"I think there's a whole, real positive energy going on and I hope to flow along with that positive energy," said Brinkley, who has said her "perfect life" was shattered by revelations her husband Peter Cook had an affair with his teenage assistant and spent thousands of dollars on Internet pornography.

"I am really looking forward to watching what happens to our country, and to our country vis-a-vis the whole world," said Brinkley, who met Obama when her daughter and ex-husband Billy Joel performed a concert for him with Bruce Springsteen.

On Friday, Brinkley unveiled the latest "got milk?" poster of herself wearing a milk mustache. She said that drinking milk was an easy way to stay healthy -- even for those hurt by the financial crisis.

"This is a great way to ensure that if ... you are cutting back and you are not able to buy an expensive piece of fish or something else, milk actually, per glass, is a very affordable way to get your nutrients," she said.

"Everybody is always rushing around," she said. "Everybody's got so much to do and you can't always put together that perfect balance of nutrients on a plate, but when you add milk to the meal, it really does complete it."
