Katharine McPhee has, allegedly, been getting parenting advice from Meghan Markle.

According to Life & Style, the American Idol winner is looking forward to the day when she would become a mom. But before this happens, McPhee has, allegedly, been hanging out with Markle so much that she gets to take care of Archie every now and then.

McPhee also, allegedly, thinks that Prince Harry and Markle’s 1-year-old son is the cutest.

As for Markle, she has, allegedly, been telling McPhee what she can expect as a first-time mom because it’s not that long ago when she became pregnant with Archie.

Earlier this month, People confirmed that McPhee and Foster are expecting their first child together. Photos of the singer with her growing baby bump were also published by the magazine.

In the snap, McPhee is wearing her workout gear while sporting her baby bump. She and Foster also visited stores to buy stuff for their baby.

McPhee and Foster tied the knot on June 28, 2019. And even though the couple seems in love, not everyone is a fan of their relationship. A lot of critics questioned their 35-year age gap but Foster immediately defended their marriage.

While speaking with USA Today, Foster said that there are a lot of things that can bring a marriage down. For instance, some couples struggle with their finances, infidelity, geography, and more.

But the only problem he and McPhee have that’s not really an issue to them is their 35-year age gap. Foster said that everything else in their marriage is in line, so their age difference won’t bring them down.

Foster, who has five grown children from his previous marriages, also said that his family had known McPhee for 15 years, so they didn’t have a hard time accepting her as part of their family.

One of Foster’s daughters, Erin, even joked about calling the singer “mommy.” Erin also said that the age gap between her dad and McPhee had benefited their relationship.

Meanwhile, Markle and McPhee went to the same school years ago. But they, reportedly, only became close because of their spouses.

While speaking with Access Hollywood, the Smash star said that Prince Harry and Foster are so cute together because they’re like father and son.

Months later, reports claimed that the Sussexes and the Fosters would be celebrating Christmas together with their other friends in Santa Barbara.
