The rapper appeared to be in good spirits as he was snapped arriving at his Calabasas, California, office on Tuesday.
Dressed in black and clutching a laptop, the 40-year-old GRAMMY winner turned and gave the peace sign as photographers congratulated him on the new arrival.
West and his 37-year-old wife, Kim Kardashian West, welcomed a daughter via surrogate early Monday morning.
“Kim was the first to have skin to skin contact with the baby and witnessed the birth,” a source tells ET. “Kanye was in the delivery room but behind a curtain. He immediately held the baby after Kim received her.”
“Kanye and I are happy to announce the arrival of our healthy, beautiful baby girl,” the reality star wrote. “We are incredibly grateful to our surrogate who made our dreams come true with the greatest gift one could give and to our wonderful doctors and nurses for their special care.”
