In the looks department, Jessica Simpson's brand-new little boy, well, aced it! "The baby is beautiful," a pal tells Us Weekly of Ace Knute Johnson, whom Simpson delivered via C-section in L.A. Sunday June 30. And he takes after his handsome father, Simpson's fiance Eric Johnson, the insider adds: "He has Eric's little chin dimple!"

Engaged since fall 2010, the Fashion Star mentor, 32, and the former NFL pro, 33, "are so happy to have a boy," notes the source. "One of each, everybody wants that!" With a middle name that honors his Swedish grandfather, Ace Knute (pronounced Ka-nute) joins big sister Maxwell Drew, 14 months.

"Maxwell is excited," the source tells Us of the blonde, blue-eyed toddler. "She doesn't totally get it and understand, but she is very excited to have a brother.

Since Ace's Sunday arrival, the second-time parents have received visits at the hospital from Simpson's parents Joe and Tina, sister Ashlee — and Simpson's still-pregnant BFF Cacee Cobb.

Expecting her first child with husband Donald Faison, Cobb, 35, sounds like she's smitten with her honorary new nephew. "IN LOVE," she tweeted Sunday in a message surrounded by hearts. Added proud grandfather Joe Simpson:"Very blessed to celebrate the birth of my new grandson."

Jessica, meanwhile, "is ecstatic," the source notes.
