As readers know, Reedus and Christensen were together from 1998 to 2003. The two share 18-year-old son Mingus, and recently reunited to attend his high school graduation.
"It may have been awkward in the beginning, but Diane and Helena have become really good friends," an insider told RadarOnline.com. "They bonded over the baby and Helena was thrilled when Norman told her the news."
Kruger, 41, and Reedus, 49, met on a movie set in 2015.
Rumors of the two getting serious began to circulate once Kruger surprisingly kicked boyfriend of 10-years Joshua Jackson to the curb, after the German model was spotted making out with Reemus at a NYC dive bar.
Now Kruger is said to be turning to Christensen for help on how to be a good parent, while the ladies friendship blossoms.
"Helena and Diane talk several times a week and love going shopping for baby stuff," the source continued. "They were casual acquaintances on the NY social circle for years so who knew they'd end up so close."
