As Lori Loughlin traveled from Vancouver to L.A. Tuesday night to surrender to federal authorities in the college bribery scandal — which got her daughter, Olivia Jade, into USC — Olivia spent the night on the yacht of the Chairman of USC’s Board of Trustees … but she’s off the boat now, TMZ has learned.

We’ve learned 19-year-old Olivia was on Rick Caruso’s yacht in the Bahamas. Caruso’s daughter, Gianna, Olivia and several other friends were spending spring break in the area.

Gianna and Olivia have been friends for quite some time, occasionally posting photos of them together on social media.
