Reports state that Christina Aguilera is playing Santa for the Spears' spawns, after ordering them Christmas gifts for them from a posh Los Angeles store.
The singer may be on tour in Europe, but she called hip celebrity baby boutique Petit Tresor to make sure the presents would arrive in time for the holidays.
Meanwhile, Britney is on tour of clubs with Paris Hilton and may not remember there even are holidays coming up.
Boutique owner Nina Takesh quoted Aguilera as saying: "I want to give them something adorable for the colder weather".
The star chose two blue cashmere schoolboy sweaters for $129 each for Sean Preston and Jayden James Federline.
No word yet on what K-Fed has picked out for his two kids, but hope Kendra Jade got a say in the matter. It's never too early to talk about the birds and the bees.
