Lady Gaga has admitted she's put on a little weight recently -- but she's not apologizing for it!
"I'm
 dieting right now, because I gained, like, 25 pounds," the singer 
revealed in a radio interview back in August ... an interview just 
making headlines now after Gaga showed off her new figure on tour in 
Amsterdam this month.
"And you know I really don't feel bad about it, not even for a second," she told host Elvis Duran.
 "I have to be on such a strict diet constantly. It's hard because it's a
 quite vigorous show, so I tend to bulk up, get muscular, and I really 
don't like that. So I'm trying to find a new balance."
Reason for her weight gain: Her dad's delicious Italian food.
"My
 father opened a restaurant, it's so amazing," she says. "It's so 
freaking delicious, but I'm telling you I gain five pounds every time I 
go in there. So my dad wants me to eat at the restaurant and I'm like 
'I've got to go where I can drink green juice!'"
 Her other weakness: Pizza.
"I love eating pasta and pizza. I'm a New York Italian girl!"
Can't blame here for that ... who doesn't like a good slice of every now and then?
