Ashlee Simpson Ross is sending L.O.V.E. to Bronx Wentz.
Ashlee shared a sweet birthday tribute to her son Bronx—who she shares with ex-husband Pete Wentz—in honor of his turning 14. The "Pieces of Me" singer posted a black and white photo of herself in a sweater and furry hat posing with the teen, who dons a simple white hoodie.
"BRONX happy birthday my grown boy," Ashlee she wrote on Nov. 21. "Can't believe you are 14. You are the kindest, and coolest. I am so lucky to be your mom." The post featured a black and white photo of Ashlee and Bronx. She's wearing a sweater and a furry hat, while the teen lounges in a white hoodie.
And Ashlee wasn't the only one celebrating Bronx's birthday as several pals chimed in with birthday wishes in the comments. "OMG," Rachel Zoe wrote, with Caecee Cobb adding,"Happy Birthday Bronx."
Ashlee's sister Jessica Simpson shared her own tribute to her nephew on Instagram, posting a snap of herself in a leather jacket and jeans, while Bronx is wearing a different white hoodie.
"Happy 14th Birthday BX!!! I love you SO very much," she wrote on Nov. 21. "You are a gift to everyone who is lucky enough know you, love you and be loved by you. Being your Aunt…has been…WILL ALWAYS BE…one of the most precious blessings of my life! Thank you for being YOU! @ashleesimpsonross you are my role model."
Bronx is the only child Ashlee and Pete—who were married from 2008 to 2011—share together. However, since their split, they've each expanded their families, with Ashlee welcoming daughter Jagger Snow, 7, and son Ziggy Blue, 2, with husband Evan Ross.
