There is very little that celebrities can keep secret nowadays including the birth of their child.
The Legally Blonde actress gave birth to her first child with husband Jim Toth on the same day which unwittingly gave Brian and Megan some space to escape out of the California hospital where the two Hollywood couples welcomed their bundles of joy.
"We got really lucky. And I've been wanting to send Reese Witherspoon flowers for, like, a month and a half," the 39-year-old told Us Weekly. "Cause she actually gave birth, I think the day before us in Santa Monica."
"We were lucky enough to go in at 2:30 in the morning to the hospital and nobody knew. We were there for two days . . . and we heard Reese was at her place and had a baby, and we got out of the hospital and nobody knew [about us]."
Brian said he though it was "unbelievable" that they managed to get home without anyone knowing.
"We weren't expecting to get away with it," the Beverly Hills 90210 star added. "So we just figured we would go with it as long as we could."
Megan finally revealed the happy news on her Facebook page two weeks later.
"We are humbled to have the opportunity to call ourselves the parents of this beautiful soul and I am forever grateful to God for allowing me to know this kind of boundless, immaculate love," the actress wrote. "Thanks to those of you who wish to send your positive energy and well wishes."
Brian added that an "ice cream cake is on the way" for Reese for unknowingly helping them out.
Reese also had a baby boy, Tennessee James, adding to her two other children; Ava and Deacon, from her marriage to Ryan Philippe.
