The youngest of the Hanson brothers has announced his engagement.

Zac Hanson, 19, is planning to wed actress girfriend Kathryn Tucker in June 2006.

The group, who had a UK number one with 'MMMBop' in 1997, revealed the news on a Mexican TV show earlier this week.

Brothers Isaac, 24, and Taylor, 21 - who is already married and a father - said they were initially "shocked" at Zac's decision but now "couldn't be happier."
