Teen Mom star Catelynn Lowell skipped a cast reunion at Briana DeJesus' house after taking aim at her "heartless" and "cruel" sister Sarah.
The reality star, 30, took to her social media for a fiery rant against her sibling following an alleged TikTok video in which Sarah 'spread lies' about her 'PTSD and trauma'.
Co-stars at the boozy bash included Jade Cline and her fiancé Sean Austin, Cheyenne Floyd and her husband Zach Davis, Briana's ex Devoin Austin and her sister Brittany DeJesus.
