Ashlee Simpson shares family snap with new baby boy Ziggy as she wishes son Bronx a happy 12th birthday… who she shares with ex Pete Wentz

Ashlee Simpson wished her eldest son Bronx Mowgli Wentz a happy 12th birthday on her Instagram page Friday.

The 36-year-old shares Bronx with her ex-husband Pete Wentz of Fall Out Boy fame and two more children with her current husband Evan Ross.

In her birthday post to Bronx, Ashlee could be seen posing up in the backyard with Evan and all her children – including her three-week-old son Ziggy.

Ashlee cradled her newborn as she stared adoringly up at the birthday boy, who was sitting next to his five-year-old sister Jagger Snow Ross.

‘Happy Birthday Bronx!’ wrote Ashlee, who is the younger sister of her fellow blonde singing sensation Jessica Simpson. 

‘You are the coolest, kindest, deep, soulful kid (almost teen) and I am so lucky to be your mom! We love you so much! Happy twelfth.’

Like his wife Evan is also a showbiz legacy – his mother is the iconic singer Diana Ross and his sister is actress Tracee Ellis Ross.

Evan married Ashlee at his mother’s Connecticut estate ‘Quarry Farm’ over the summer of 2014, and 11 months later Jagger was born.

The mother-of-three announced her latest pregnancy this April and gave birth to her youngest little bundle of joy on October 29.

She went public with the birth on Instagram this Halloween, posting a sweet snap of her sleeping baby with each of his parents resting a hand on him.

Ashlee gushed in the caption: ’10-29-2020 ZIGGY BLU ROSS. Our sweet boy has arrived! I’m over the MOON we are so blessed!’

The showbiz blonde married Pete in 2008 in a ceremony performed by her ex-pastor father Joe at her parents’ house.

In her hit memoir Open Book, Jessica Simpson recalled that Joe brought a male model she had never met to her 2014 wedding to Eric Johnson.

‘I reminded myself that I needed to accept my father for who he was as he worked it out in real-time,’ wrote Jessica of Joe.

Although Ashlee and Pete divorced in 2011 they have remained amicable co-parents and last year he told Us Weekly that she is ‘a great mom.’
