American socialite Paris Hilton has introduced her second child, London Marilyn, to the public.

In an Instagram post, Hilton shared snaps with her family explaining the reason behind her child's name.

"Introducing London Marilyn Hilton-Reum, I’ve dreamed of having a daughter named London for as long as I can remember," Hilton said.

"I’m so grateful she is here ... I truly cherish every moment I spend with her. Together with Phoenix, my angel babies have shown me a love that I never even knew could run so deep before I became their mother," she added.

Hilton also shared her new learnings about motherhood after the birth of her two kids.

"My incredible journey through motherhood has inspired a new, deeply personal song with my dear friend Sia called 'Fame Won’t Love You.' The song serves as a reminder that the special bond I feel with my children, my husband & my family is more valuable than anything else in the world," she said.

"It’s an anthem that will empower you to hold your most sacred relationships even closer to your heart - whether with family, friends, or yourself. I hope you love it as much as I do."
