The Pulp Fiction actor revealed Preston is three months pregnant last week (end23May10), marking the end of a devastating period which began with the death of their teenage son Jett last year (Jan09) and ended with an airport tragedy in Maine earlier this month (13May10), which claimed the lives of the family's two pet dogs.
Travolta's Look Who's Talking co-star Kirstie Alley was the first to coo about the news, writing in a post on her Twitter.com page, "YAY!!! SOOOOO happy for them!!! YAY!!!"
And now messages of support have flooded in from the actor's former co-stars Hugh Jackman, Christopher Walken and Lori Loughlin.
Jackman, who starred with Travolta in Swordfish, says, "I'm very thrilled for him. I know John – he's an amazing dad and so that's one lucky kid. I'm very, very, very happy for them. Very excited."
Meanwhile, Travolta's Hairspray colleague Walken says, "Wonderful news."
And Lori Loughlin, who appeared with both Travolta and Preston in 2009's Old Dogs adds, "Kelly and John are wonderful people. They deserve all the joy this new baby will bring them!"
