Blooming: Pregnant April Love Geary, 23, looked sensational in a very scanty black bikini as she enjoyed a sun-soaked break in St Barths with boyfriend Robin Thicke, 41

She is expecting her second child with beau Robin Thicke, with news surfacing revealing she is pregnant again in August.

And showcasing her blossoming baby bump while on a sun-kissed break in St Barthelemy, April Love Geary looked sensational in a very scanty black bikini.

The model, 23, sizzled in her barely-there swimwear as she joined Blurred Lines hit-maker Robin, 41, around the pool, where he was seen doting on the couple’s eight-month-old daughter Mia.

Parading her pregnancy frame, April undoubtedly had all eyes on her as she soaked up the sunshine in her minimal beach attire.

The brunette beauty favoured a black-two piece that framed her bust with its halter-neck style string bikini top and left her bump firmly on display with its low-rise briefs.

April was seen resting her hand on her baby bump as she kicked back in the sunshine while overseas, indulging in a spot of R&R ahead of welcoming her new addition.

She left her dark tresses down to fall past her shoulders in loose curls and sported a minimal yet glowing make-up look to accentuate her natural features.

April was seen taking part in a photoshoot poolside with her love Robin and their eldest daughter and was seen sporting two beach ensembles.

One outfit choice saw the star slip into a striped blue and white bardot beach dress that perfectly skimmed over her bump and boasted ruched sleeves. Another saw April sport a purple patterned mini dress that left her catwalk worthy pins on view.

She was seen stripping off by the pool and lifting the stylish number over her head to revealed her black bikini underneath. Enjoying a dip as she cooled off from the sunnier climes, April looked every inch the beach beauty as she posed in the pool while wearing a pair of chic shades.

When he wasn’t showering his girlfriend with affection, Robin was seen doting on the pair’s daughter Mia, eight months. He was spotted cradling little Mia in his arms and lovingly lifting her into the air as they played in the sunshine.

Robin couldn’t hide his delight as he carried Mia around the resort and had the tot sitting on his lap.

Mia is the star’s second child, as he is also father to son Julian, eight, whom he shares with his ex-wife of ten years Paula Patton.
