"The only thing that was really on my mind was wanting to get it over with," Hamilton said.
Lopez said the violent vomiting left her in a precarious, sticky situation.
"I just went into help mode," said Lopez. "I didn't know how to react. I was in shock."
But as any loving girlfriend would do, Lopez patted her nauseous boyfriend on the back while passing him a sweater to wipe his face.
The good news? She said yes!
While their first kiss as an engaged couple probably had a slight aftertaste of that day's lunch, Hamilton says he's over the mood and already starting to plan his life with Lopez.
"I have a son from a previous relationship and me and Rheanna don't have any kids together," Hamilton told ABC News. "So maybe starting a family with a child of our own and being a role model for both of them, and for her."
