There is only one Christina Aguilera in the world, but the pop diva has a few siblings she can relate to (pun intended).

While none of them are pop divas, she has one biological sister and one half-brother, both of whom she loves dearly!

Her sister, Rachel, is younger than her, and the two are very close. We don’t know much about Xtina’s sis since the family is notoriously private, but they look very similar!

After her parents divorced, her mom, Shelly, remarried Jim Kearns. His son, Michael — also younger than Christina — is now her half-brother, and when our favorite Voice coach was honored with a star on Hollywood’s Walk of Fame in 2010, her entire family was right there with her to celebrate. Aww!

Did you know about Xtina’s siblings? Tell us below!
