Ritchie, 39, attended neither Madonna's induction into the Rock and Roll Hall of Fame last week nor her star-studded United Nations fundraiser in early February.
Rosenberg explained that, until recently, Madonna, 49, and Ritchie were living in separate countries: The Material Girl toured the U.S. to promote her upcoming album "Hard Candy," while the director was stationed in England putting the finishing touches on his new film "RocknRolla," filming a Nike commercial and "working on several scripts."
Today, the Ritchies are "joyfully back together at home in London. All is well and wonderful in the Ritchie household," Rosenberg said.
The couple have a son, Rocco, 7, and Madonna has a daughter, Lourdes, 11. In 2006, they began raising a Malawian boy they want to adopt.
