Jeff Bezos's fiancee Lauren Sanchez gets emotional over son's college graduation

Amazon founder Jeff Bezos's fiancee Lauren Sanchez got emotional as she celebrated her eldest child Nikko Gonzalez's college graduation earlier this week, Business Insider reported. 

In a heart-touching post on her Instagram, Sanchez shared a series of childhood images of her 23-year-old son whom he shares with ex-boyfriend and ex-National Football Association (NFL) star Tony Gonzalez.

One image showed the philanthropist holding a toddler-aged Nikko, while in another picture, Nikko and his dad smile for the camera.

The Emmy award-winning journalist captioned the post: "Really emotional day for me. My firstborn graduated from college today! My heart is overflowing with pride for this incredible young man." 

"It seems like yesterday your dad and I were carrying you in our arms. I just want you to know how immensely proud I am of you for achieving this milestone," her post added.

"This is just the beginning, Nikko, and I hope you continue chasing your dreams with relentless originality. I love you so much."

The 54-year-old Sanchez and her former partner have maintained a friendly co-parenting relationship since their split. 

She is often seen socialising together with her 48-year-old ex-partner and his wife October. 

They are so close that the former Kansas City Chiefs tight end was even on Bezos's $500 million superyacht together with the newly-engaged couple, Page Six reported.
