If you want to get anywhere near Christina Aguilera's growing baby bump, you'll have to get through Max Bratman first.
The pregnant singer shared an adorable photo of her and her son while running errands together in Studio City, Calif., (along with fiancé, Matthew Rutler), and while getting snapped by shutterbugs, Xtina's little boy protectively shields his mama's bun in the oven—so cute! It definitely seems like Max is more than ready to take on his big brother duties.
"Max already protecting mommy & his little sister! He's the greatest captioned the photo, that had the text "big brother love" on it, on Twitter.," Aguilera
Though they had a great time together as a trio, Aguilera is ready to welcome her mini-me. "I'm really excited to meet our baby girl," she said in June. "This has been a very easy and enjoyable pregnancy."
The couple celebrated their daughter's imminent arrival on Saturday with a co-ed baby shower held at the home of the singer's stylist. Nearly 50 family members and close friends attended the intimate gathering, which was humorously highlighted with a cake that was one for the books. Their tasty treat was decorated with a figure of a woman (presumably Christina) giving birth on a rug atop a hardwood floor, the baby's head (complete with a full head of hair) poking out from you-know-where.
"Push Xtina, push," the writing on the cake encouraged.
"Christina is doing great," a source has told E! News. "She's really glowing. She's feeling great and isn't tired at all. She can't wait to meet her baby girl."
We can't wait, either!
