Pink is one doting mother! The mother of two took to her Instagram page to give fans an insight into her weekend, which included a "big sister party" for her five-year-old daughter Willow. In the caption, she gushed: "Congrats Big Sis! #bigsisterparty."
The sweet photograph sees the singer cradling her newborn son Jameson Moon in her arms, while her little girl sits next to her, smiling widely and holding a large chocolate cake on her lap.
The family celebration comes just a few days after Pink and her husband Carey Hart celebrated their 11th wedding anniversary. Alongside a photo of herself and Carey, Pink gushed: "I really like you this week. #happyanniversarymylove I'm very lucky to be able to say that you're mine. Thanks for sticking around."
Pink - whose real name is Alecia Beth Moore - married motorcycle racer Carey in 2006. Although they separated in February 2008, the couple later reconciled after seeking marriage counselling. They welcomed their first child Willow in 2011 before the arrival of their son in December.
The American star, 37, surprised fans with the news of her second pregnancy back in November after sharing a photo revealing her growing baby bump. She captioned the sweet snap with a simple: "Surprise!" Carey, 41, previously revealed to People magazine that he had hoped that the pair were having a son as they already share a daughter. He said: "We got one princess, so hopefully we'll have a little guy coming. I don't want any competition for my daughter. I'm nervous for what it's going to be."
