Olympic swimmer Michael Phelps might become a daddy someday.

Michael Phelps' Rumored Ex Says 'Things Are Coming Back To Normal'

On Tuesday, the athlete's fiancee, Nicole Johnson, took to her Instagram page to post a photo of a heartfelt quote about letting people come into her life. The quote reads, "An invisible thread connects those who are destined to meet, regardless of time, place, or circumstance. The thread may stretch or tangle, but it will never break. May you be open to each thread that comes into your life- the golden ones and the coarse ones- and may you weave them into a brilliant and beautiful life."

In the caption, Johnson wrote about how grateful she is for all the people who made a difference and made her feel "incredible." She added that she wants to meet new people in the future- including kids.

"I especially look forward to adding children to my weaving," she wrote.

This seemingly implies that she and Phelps might want to be parents after tying the knot.

Meanwhile, things seem to be going swimmingly in the couple's engagement as they prepare to exchange vows. They've been posting random photos on social media here and there where they look more in love than ever.
