The Pirates of the Caribbean star took to Instagram to share a sweet birthday message he penned for his ex, with whom he shares a 6-year-old son, Flynn. The Australian supermodel and Victoria's Secret Angel turned 34 on Thursday.
"#HAPPY BIRTHDAY to an amazing mother, co-parent and friend," Bloom captioned a photo of sweet, handmade sign that read "I [love] u mum" written in wooden sticks.
Bloom and Kerr began dating in 2007 and eventually got engaged in 2010. The couple wed one month later. The following year, they welcomed their adorable baby boy.
While the couple got divorced in 2013, they have remained close friends and have actively worked together to amicably co-parent their son.
In 2015, Kerr began a relationship with Snapchat co-founder Evan Spiegel, and the two got engaged in July 2016. Bloom struck up a relationship with singer Katy Perry in January 2016, but the couple announced their split in February.
Last August, Kerr opened up to Harper's Bazaar about her and Bloom's efforts to raise their son together despite their divorce, and how it even dictated where she wanted to live with her new fiancé, "because we wanted to be close as a family." Check out the video below to hear more.
