Sweetin, who turns 40 on Wednesday, announced her engagement to boyfriend Mescal Wasilewski on Instagram.
“‘In all the world there is no heart for me like yours. In all the world there is no love for you like mine,’” Sweetin wrote, quoting poet Maya Angelou in her post.
This will be Sweetin’s fourth marriage, CNN reported, noting that she was previously married to Shaun Holguin from 2002 to 2006, Cody Herpin from 2007 to 2010 and Morty Coyle from 2012 to 2016.
Meanwhile, friends and co-stars gushed in the post’s comments about the pending nuptials.
“Congratulations sis Love you,” wrote “Full House” co-star Candace Cameron Bure, while “Wonder Years” star Danica McKellar wrote, “Congratulations!!!”
Sweetin’s announcement comes days after the funeral for Bob Saget, who played TV father Danny Tanner to Sweetin’s Stephanie Tanner on the long-running fan favorite, “Full House” and its spinoff “Fuller House.”
