The singer posed for a series of photos, which she then shared on her Tumblr page.
In one photo, Beyonce, 32, is making a funny face at Blue Ivy, whose little hands can be seen in the corner of the pic.
Another snap shows the star balancing on a float in the swimming pool, wearing a giant sun hat.
She also shared a picture of herself and Jay-Z, sitting in the edge of the pool, looking into the horizon.
Along with photos by the swimming pool, Beyonce also posted an adorable pic of Blue Ivy wearing, what look like, her mum's glasses.
The Destiny's Child singer has been busy with her world tour, that began in April last year and finishes in Lisbon, Portugal on Thursday (27 March).
But, luckily, she's been able to take Jay-Z and two-year-old Blue Ivy with her along the way.
