Christina Aguilera may have had good reason for defending Britney Spears’ mothering earlier this week; the former Mickey Mouse Club co-stars are rumored to have ended their long-time feud and are friends again. Britney is also rumored to be contributing to a CD of original lullabies that soon-to-be Mama Christina Aguilera has proposed.

According to celebrity tattles:

Aguilera reached out to Spears, and the two reportedly have spoken on the phone, e-mailed a lot and smoothed things over. So much so that Spears is both hosting the upcoming Las Vegas opening of the LAX nightclub (in which Aguilera is a part owner) and supposedly has agreed to contribute to the proposed CD of original lullabies Aguilera is developing.
