The Amazon billionaire, 57, locked lips with Sánchez, 51, on Friday after leaving Cipriani in downtown Manhattan, where they had lunch with friends. The couple held hands as they strolled down the sidewalk with their group.
Bezos kept it casual in a snug black polo shirt, partially tucked into belted jeans, finished with black shoes and round silver-framed sunglasses. Sánchez layered a white peacoat over an orange minidress with a matching Hermès Birkin bag. She completed the look with chunky black square sunglasses and a pair of white sneakers.
"Good luck on the launch my love. This morning you and your @blueorigin team will be launching 4 incredible people into space, just yards away from where we were riding horses yesterday. Truly incredible! You never cease to amaze me," she wrote.
The Emmy Award-winning journalist was also there to greet Bezos with a hug when he returned safely to Earth from his own maiden voyage to the edge of space in July.
"Our family was happy to see us. That's a good sign," Bezos joked during the post-flight press conference. "I wasn't that nervous, but my family was somewhat anxious about this and so it was so sweet actually to get hugged by them after landing, especially my kids and Lauren and my mom and dad and really all of you guys. We have a bunch of close friends here too, it just makes me realize how much I love you and how much I'm loved."

Bezos and his partner, who spent time together in Texas this week ahead of the launch, took their relationship public in January 2019. "They're madly in love and stronger than ever," a source told PEOPLE at the time.
