The second image in her Thursday post shows Kotb and Bush Hager, 37, both squeezing in for the fun selfie session.

“CUTEST PHOTO OF ALL TIME,” commented the Today with Hoda & Jenna account, tacking on both heart-eye and heart emoijs.
“What we’ve been waiting for,” wrote the O, The Oprah Magazine account, with a heart-eyed smiley.
Haley’s meeting with Hal comes days after the baby boy was born. His first visitor? Proud aunt Barbara Pierce Bush Coyne, who brought her twin sister “donuts and tacos” when she arrived at the hospital.
The new mom of three tacked on the hashtags “#sistersfirst” and “#tacosforthewin” in her post, which included a photo of the twins side-by-side as Bush Hager held her son on her chest and Bush Coyne lovingly watched on, with her arms around them both.
