Did someone take my daughter to France?

Bennett was absolutely adorable tonight. She was playing and talking and we were just delighting in her. When it was bedtime I told her that it was time to go night-night. She said, "Okay, night-night." I picked her up and we started up the stairs. She said, "Night Night, Daddy. Night Night, Will. Night Night, Pierre." I started laughing and asked Rob if he had heard that. The she said, "Wuv oooo, Daddy. Wuv ooo, Will. Wuv ooo, Pierre." I asked Rob if she had just told Pierre that she loved him. Rob agreed that indeed Pierre had been given some love.

I carried Bennett to her changing table and as I was changing her diaper, this is what I heard-

Bennett: Night Night, Pierre. Clock. Bye-Bye, Pierre. PUPPY!! Book. Book. Book. Book. Pierre. Wuv oooo, Pierre. Help! Help! Shoes. Book. Chips. Yucky, diaper. Pierre, Night Night. Book! Please, book! Pierre.

I was laughing so hard that Bennett frowned at me and quit talking. But seriously, Pierre? Is this her first imaginary friend? And why is he French?
