Tori Spelling is showing off her pregnancy curves in a barely-there bikini. The actress and reality star, currently pregnant with her and Dean McDermott’s fourth child, was photographed in Los Angeles on Memorial Day.

The 45-year-old, seen here with Dean and 7-month-old daughter Hattie, doesn’t yet know if she’s expecting a boy or girl this time around. The mother of 5-year-old son Liam and 3-year-old daughter Stella explained previously, “We would like a little boy, and Stella…she’s now a middle child and when we told her about the pregnancy she said ‘I hope it’s a little boy for Liam.’”

Tori Spelling is pictured here wearing Sanuk Yoga Mat sandals, which retail online for $30 – $32 www.sanuk.com.
