Simon Cowell is embracing fatherhood.

The former “American Idol” judge, 54, tweeted a photo of his son, Eric, during bath time on Thursday.

The baby, now four months, lies in a little green bath cradle while covered with a teal towel.

“Bath Time!” Cowell captioned the photo.

Cowell, who is planning to reboot “Ultimate DJ,” hired an expert, Edward Alva, to help his two Yorkies become comfortable with his new son.

“Edward advised Simon on how to familiarize the dogs with Eric, telling Simon to put one of Eric’s blankets in the pup’s basket so they could get used to the newborn’s smell,” a source said.
