Twelve years after Carnie Wilson underwent gastric bypass surgery
and famously lost 150 lbs., the singer has done it again: On January 18, Wilson went under the knife for lap-band surgery, PEOPLE confirms exclusively.
Since having the procedure – during which a silicone band is placed around the stomach to create a pouch the size of a golf ball – Wilson, 43, has lost 30 lbs. and counting.
"It was the right decision for me and I'm doing really well so far," Wilson tells PEOPLE. "It's all about taking good care of myself."
The singer, who is reuniting with Wilson Phillips to promote their new album, Dedicated
and their TV Guide Network reality show, Wilson Phillips: Still Holding On
, has struggled to lose
the post-pregnancy pounds. Wilson has two daughters, Lola, 6, and Luciana, 2
, with her musician husband Rob Bonfiglio, 44.
"Having children derailed me a bit," Wilson told PEOPLE in 2010 of her weight struggles. "I'm just frustrated with these pounds."
Wilson Phillips's new album drops April 3 and their series premieres on April 8.
