Such a pretty little mom-to-be! Pretty Little Liars actress Tammin Sursok — who is expecting her first child with husband Sean McEwen — treated herself to a day of rest and relaxation off the coast of California on Wednesday, July 31.

Hitting the Pacific Ocean for a romantic boat ride with McEwen, the former Young and the Restless star, 29, bared her growing baby bump in a teeny black bikini. She looked happy and carefree as she packed on the PDA with her actor/director husband, who donned white shorts, a white polo, and tan boat shoes.

Sursok, who plays Jenna on ABC Family’s Pretty Little Liars, first confirmed her pregnancy back in June. “We are so excited and feel very blessed to be having a baby,” she told Us Weekly at the time. “We will be happy with either a boy or a girl.”

Sursok has since found out the gender, but she’s keeping, ahem, mum for now. “Guess what,” she tweeted on June 19. “I know if it’s a boy or a girl and I know the name…Got a secret, gotta keep it…”

This will be the couple’s first child. But Sursok has said her husband — whom she married in Italy in August 2011 — wants a big family.

“I think my husband is definitely, definitely pushing for [kids]. I keep running away from him,” the South African-born Aussie actress joked in a recent radio interview. “I think [it’ll happen] soon. It’d be good to have a couple. We want like three or four…But a lot of Tammins running around — I don’t know if the world needs anymore.”
