Bruce Willis' wife Emma Heming has taken to Twitter to thank everyone for their well-wishes following the birth of her second child.
The star also said that Bruce Willis, who now has a total of five daughters, "is still the man of the house".

"My husband is still the man of the house! Thank you for all the well wishes. We are all doing wonderfully #BlessedWithGirls," read the tweet.
Little Evelyn Penn Willis made her grand entrance into the world on 5 May in Los Angeles.
The newborn weighed in at 8lbs, and both mum and daughter were said to be doing well when the news was announced on Wednesday evening.

She is a sister to the couple's two-year-old Mabel - as well as Rumer, 25, Scout, 22 and 20-year-old Tallulah from the Die Hard star's first marriage to Demi Moore.
Scout seemed the most excited about the news as she quickly shared it with her Twitter followers: "And the Willis girl coven keeps on growing."
Bruce is certain to take the new arrival in his stride, having said that he relishes fatherhood even more at his age.
"I'm happier than I've ever been. I'm changing diapers like a champ," the 59-year-old actor said recently.
Bruce Willis and Emma Heming have been married for five years
"What I've also discovered is how much love I feel for our baby. I think I'm even more open and more giving as a father now. I pay more attention now because I value it more and I'm less caught up with my career."
He and Emma, 35, a model, tied the knot five years ago and the marriage has given new meaning to Bruce's life after his divorce from Demi in 2000.
