Music mogul Sean "Diddy" Combs and his longtime girlfriend/baby mama Kim Porter couldn’t be happier with each other and the impending birth of their twin daughters in December, however the couple reportedly can’t agree on one thing: what to name their baby girls.

"Sean and Kim adore each other, but they can’t agree on names," an insider told In Touch.

The insider says Diddy wants to name the girls after jewelry and christen their girls Diamond and Ruby. However, Kim hates those names and wants to give their daughters traditional monikers like Grace and Emily. The two are reportedly considering a compromise, with Kim naming one baby and Diddy naming the other.

The couple already have a son together, 8-year-old Christian, and also raise Justin, 12, and Quincy, 15, from their previous relationships.
