Pregnant Alanis Morissette shows off her baby bump in tight mini dress as she enjoys a day of water sports with shirtless pal Woody Harrelson in Hawaii

She's enjoying some down time while waiting for the birth of her second child.

And what better way for Alanis Morissette to relax than with a fun-filled boat trip with her nearest and dearest in Hawaii.

The Canadian songstress basked in the sunshine as she hit the water with her husband Mario 'Souleye' Treadway and their nearest and dearest, including close friend Woody Harrelson on Wednesday.

Alanis, 41, didn't let pregnancy get in the way of some watersports, as headed into the sea for a spot of snorkeling.

With her flippers on and a mask in hand, Alanis layered a grey mini dress over a black bikini top as she headed down the steps of the boat.

Earlier in the day the Ironic singer sported a pink t-shirt and shades, with her short curly locks left loose as she chatted to Woody while waiting to set sail on the tour boat.

The Hunger Games actor stripped off his t-shirt to show off his aquatic acrobatic skills once on board, back-flipping into the ocean.

The 54-year-old, who has a home on Maui's north shore with his wife Laura and their three daughters, looked in great shape with his tanned and toned torso.

Alanis was also spotted kicking back with her rapper husband of five years, who dressed casually in a blue t-shirt for the day at sea.

It looked like an eventful boat trip as Alanis later shared photos on her Instagram account of some whales the group spotted, gushing to her fans:  

'epic-est whale watching.... jaw-droppingly stunning. one longer than the boat swam underneath us... whimsy preciousness. #speechless #heartbeatingsoquickly #mauiblessed.'

The talented singer is expecting her second child with husband Mario, happily announcing the news on her official website last month with the help of an animated music video telling the story of the couple's life together.

Alanis, 41, wrote the song with Guy Sigsworth in 2010 'on the sly' to surprise her rapper beau before the birth of their first child in December 2010.

The animation was done by Brendan Huza shortly after and the singer explained that it will evolve throughout each chapter of her life.
