Malaika Arora and ex-husband Arbaaz Khan get together to ring in son, Arhaan Khan's 15th birthday

Though Malaika Arora and Arbaaz Khan have bid adieu to their 13 years of marriage, there is one thing that has still got them connected- their son Arhaan Khan. Today, November 9 being Arhaan's 15th birthday, both, Malaika and Arbaaz brought their son's special day together. One of the yummy mummies of Bollywood, Malaika shared a beautiful collection of pictures of hers and Arbaaz with Arhaan. While few of the images were from last night, where they cut his cake together, others were from the earlier picture library.
