Geary announced she was pregnant via the social media site also on Thursday, with a sonogram of their child revealing she is due to give birth on March 1 2018. 

The date she is due to give birth is the singer’s late dad Alan Thicke’s birthday. She did not reveal the sex.

Three weeks ago, Thicke and his ex-wife reached a custody agreement over their son, Julian.

E! News reported that Thicke will have the seven-year old Monday to Wednesday while Patton will have him Wednesday to Friday. They will then alternate weekends.

This comes seven months after a judge granted Patton’s request for a temporary restraining order against her ex-husband.
