Britney Spears reacts to Kevin Federline’s claims about their relationship with their teenage sons.

Britney Spears said she was saddened at the "hurtful” claims made by Kevin Federline, her ex-husband.

Federline's comments on his ex-wife, and their relationship with their sons, went viral Saturday.

Federline stated that the boys decided not to see her at this time. They haven't seen her in a while. They decided not to attend her wedding.

Federline and Spears have two sons, Sean (16) and Jayden (15).

Federline, 44-year-old former dancer, said later, "This entire thing has been difficult to watch,

harder for me to live through, and harder to watch my boys do than any other."

He also claimed that part of the fallout was due to her Instagram account.

He said, "It's been difficult." It's been the most difficult thing I've ever done in my life."

Spears replied late Saturday via her Instagram Story.
