Tim and Helena: Party People

"The King's Speech" actress Helena Bonham Carter and her long-time partner, director Tim Burton, were spotted doing something relatively ordinary on Sunday -- the odd couple took their kids, Billy, 7, and Nell, 3, to a friend's birthday party in Belsize Park in London, and returned home later in the afternoon bearing a bunch of colorful balloons.

Bonham Carter and her "Alice in Wonderland" director beau, who have been together since 2001, famously live in separate neighboring houses that are linked by a connecting door, allowing the couple their individual space when they need it.

Proving that it's never too late to learn new parenting tricks, the eccentric actress recently admitted that she took a few parenting classes during a break between film projects. "I'm not working right now," Helena told E! Online, adding, "I need to be a mom. It's much harder being a mom than an actress." Why the sudden urge to learn after all this time? "You know, no one taught me what to do," explained the actress, who called the classes "fun."

"They're teaching me some really interesting things, like it's not your job to know everything ... You've got to get them to think for themselves," said Bonham Carter, adding, "What a relief. I don't have to know everything!"
