Mariah Carey is delighting in some downtime with her family before judging duties begin on the upcoming season of American Idol, and what better way to relax than napping and swimming with your adorable toddlers?

The Grammy winner uploaded these sweet pics of her twins to her Twitter account, and we can't believe how much the little ones look like their famous mom! In one shot, Nick Cannon's wifey shares a snuggle in bed with her son Moroccan as she pretends to sleep. In the other, the 42-year-old singer dons a bikini and white lace cover up while she watches her daughter Monroe float in a raft in the pool. Aww!

We can't wait to see Mimi find the next big superstar on the singing competition!
