Hello, Mr. Nice Guy! See Pics of Softy Simon Cowell With His Baby

Simon Cowell is clearly a new man.

The former "American Idol" judge and TV producer once known for his painfully honest (and occasionally a bit mean) persona is a father now, and based on the black and white photos he shared on Twitter on Sunday, he's basically one Big. Giant. Softy.

Cowell, 54, and his girlfriend, Lauren Silverman, welcomed son Eric – who was named after the star's late father – on Friday and, like the tot's birth date, he's just filled with love.

"I never knew how much love and pride I would feel," the first-time dad confessed alongside the shot of himself cradling his little one.

But, seeing as this is clearly a new Simon, that's not even the only sentiment he shared.

Seriously, how sweet and tender are these?! It looks like Simon won't exactly be keeping the promise he made to the Times of London back in September. "I can assure: I won't go soft," he insisted. So much for that.

All that said, don't expect to hear stories of Cowell doing diaper duty.

"I'm not doing that, 100 percent absolutely not going near that," he told the BBC.
