For Simon Cowell
, it's the more, the furrier!
The 53-year-old introduced two new puppies he recently adopted Thursday over Twitter
, asking fans, "Any suggestions for names?"
Cowell, who is expecting his first child
with girlfriend Lauren Silverman, has spoken out in the past
about the importance of adopting a dog rather than buying it from a pet shop. Last month, he sent out a message that he was looking to expand his family.
"I am going to get two dogs when I get back [to L.A.]," he Tweeted
on Sept. 3. "Probably cairn terriers. If any rescue shelters have some who need a home let me know."
A longtime supporter of animal charities, the X Factor
judge reportedly helped set up a dog sanctuary on Barbados and donated
$30,000 to Exorcist
star Linda Blair's California animal shelter.
He also revealed in a recent interview that he intends to leave his $300 million fortune to charity.
"I'm going to leave my money to somebody," he told Esquire
magazine. "A charity – probably kids and dogs. I don't believe in passing on from one generation to another."
