Simon Cowell took to Twitter Thursday to share a new photo of his bundle of joy.

"Bath Time!" the music mogul captioned the picture of 4-month-old Eric in the tub.

Cowell, 54, and Laura Silverman welcomed Eric on February 14 after the two had a scandalous affair while she was still married to Cowell's best friend, Andrew Silverman.

The former "The X Factor" judge told the Mirror in April that he regretted how his relationship with Silverman began, but was happy to be a father.

Eric is Cowell's first son and the second for Silverman, who has a 7-year-old son from her previous marriage.
