Nicole Kidman and Keith Urban welcomed a baby girl into the world today! Sunday Rose Kidman-Urban made her debut in Nashville, and she weighed in a 6 pounds, 7 ounces. Congratulations to the happy family! Is it just us, or does Keith look a bit like Billy Ray Cyrus with that highlighted hair?

Nicole wasn’t just blessed with a healthy baby girl; she also received a sweet “push present” from hubby Keith. InTouch reports:

“Keith Urban has purchased a surprise present to give to his wife in the delivery room — a $73,000 Cartier Trinity ring! “It’s three rings intertwined, so it’s very symbolic,” the insider says of the popular design, which is set with multi-colored pavé diamonds and is meant to represent the three stages of a relationship: yellow gold for friendship, rose gold for love and white gold for fidelity.

“It’s three turned into one and that’s how it will be with Keith, Nicole and the new baby,” notes the insider. The Trinity ring was created by Cartier in 1924 and is still one of its most recognized designs today.”
