Shayne Lamas and husband Nik Richie are ending their relationship after more than a decade together.
The former Bachelor star, 35, announced the news on Instagram Monday.
"Friends & Family, after 11 years together Nik and I have come to a loving conclusion to get a divorce, we have nothing but love and respect for one another and will cherish the years shared, memories made, and the children we are so proud of," Lamas wrote alongside a photo of herself and Richie wearing boxing gloves.
"This is just the situation of two people growing apart," she continued. "We ask everyone to respect our privacy as we navigate our new normal within our family."
Lamas and Richie tied the knot in 2010, two years after Lamas won season 12 of The Bachelor in 2008.
Then-Bachelor Matt Grant and Lamas announced their split later that year.
