“She’s here! Luna Simone Stephens, we are so in love with you! And sleepy. Very sleepy,” Teigen 30, posted on Instagram Sunday, alongside a monitor screen showing drawings of pandas and of a rainbow, reading, “My weight is 6 lb 11 oz.” Legend, 37, tweeted the birth date Sunday, writing, “Our new love is here!

Teigen responded with a joke at first, tweeting, “To everyone asking, John is healing perfectly.” She quickly followed up with, “thank you for all the well wishes!!! we are so happy and excited! i dunno what to tweet now. does my twitter change? this is so awkward.”

She and Legend — a multiple Grammy Award-winner, most recently as co-performer of “Glory,” 2015’s Best Song Written For Visual Media — married in Lake Como, Italy, on Sept. 14, 2013. They announced in October they were expecting. Teigen had undergone in vitro fertilization to become pregnant, telling People magazine in February, “Not only am I having a girl, but I picked the girl from her little embryo. I picked her and was like, ‘Let’s put in the girl.’ ”
