Dressed in all black and looking gorgeous as ever, Caitlyn Jenner, 68, and model girlfriend Sophia Hutchins, 22, were spotted leaving Craig’s restaurant this Thursday in Los Angeles. The two looked giddy and in love, days after they attended Kylie’s 21st birthday bash together.

While the age gap between Jenner and Hutchins has garnered them a whole lot of criticism, the love birds have stayed strong and confident about their romance.

A source recently told RadarOnline.com that the secret to their happy relationship is simply unconditional trust!

“Cait has the house, the money, the cars, the connections. She's got everything. Yet she doesn't use that to control Sophia,” said the insider. “Cait lets her come and go as she pleases and doesn't put any conditions on their relationship because that could lead to unhappiness and cheating—you know, like Tristan did to Khloe.”

RadarOnline.com readers know Jenner has been estranged from her famous family ever since her transition, but instead, she’s focused all her energies on being the perfect partner to Hutchins.

“Cait would never wish anything bad on Khloe but, it's not the first time it's happened nor the last. Cait's seen just how controlling, manipulative and flat out bossy the Kardashian girls are and told Sophia she will not try to control her like Kris did him and how Khloe does her men,” added the source.

This July, Sophia Hutchins confirmed her relationship with Caitlyn Jenner, even suggesting that the two live together inside the star’s L.A. mansion and share ownership of pet pup Bertha.
