Do Kiss the Superstar by Cami Checketts

Caleb Jewel has it all: fame, fortune, family, fans. When he meets the beautiful Emily Gehring and her son, Krew, he falls for the duo hard and fast. There’s only one problem—she promised her ex she won’t date for a year, and he promised he won’t take their son for his custody visits. Emily will do anything to protect her little boy from being alone with her ex.
Caleb will have to forget about his jokes and pranks and exercise self-control nobody believes he has, or risk losing the only woman who’s ever tested his patience and made him fall in love.
