Jennifer Lopez baked her twins' birthday cupcakes on Friday, Feb. 22.

Famous singer and actress Jennifer Lopez celebrated her twins' fifth birthday with the homemade cupcakes, which the children, named Max and Emme, took to their school.

Lopez showed off her hard work on Twitter, posting a picture of the frosted cupcakes.

"Happy Birthday Coconuts! 5 years of joy and true love! School cupcakes. Mom duties. Best feeling ever," Lopez commented.

Lopez shares custody of her children with ex-husband Marc Anthony. After seven years of marriage, Lopez split with Anthony in July 2011.

Marc Anthony filed for divorce in April 2012, but the papers haven't been finalized.

The entire family gathered for a party to celebrate the birthday of Anthony's son Christian, whose mother is the former Miss Universe Dayanara Torress.

According to Us Weekly, Lopez and Anthony both brought their new significant others to Christian's birthday party.

Lopez posed with her boyfriend and former background dancer Casper Smart, while Anthony brought 24-year-old Shannan de Lima as his date.

The ex-couple has decided to remain friends to benefit their children, Max and Emme. Lopez has stated, "He will always be in our lives. He will always hold a special place in my heart as the father of my children. You know, we respect each other."

The arrangement seems to be going well, as last year the couple worked together on a reality TV show called Q'Viva that searches for and showcases the best singers and dancers in Latin America.

Anthony said, "We're just meant to be in each other's lives in different levels," of their professional relationship.
