Myleene is currently staying in Sian Ka'an in Mexico with her two daughters, Ava and Hero, and it seems they are having a...whale...of a time!
Earlier today (2 January), Myleene shared a video she took while out at sea on a boat with her girls.
While sailing the waves, the trio were lucky enough to get a glimpse of a pod of dolphins as they swam alongside their vessel.
In the clip, which she posted on Instagram, Myleene is shielding her eyes with a pair of gorgeous leopard print sunnies and has her hair tied up in a ponytail.
Myleene's daughters are wearing life jackets and one can be heard squealing: "Dolphins!" Aww, too cute.
Alongside the video, Myleene commented: "Completely magical #dolphins #inthewild #siankaan."
Meanwhile, the classical musician has also shared several photographs taken during her winter sun holiday with Ava and Hero.
One snap shows three pairs of feet - all with painted toenails - taken as Myleene and her daughters relaxed together in a hammock.
In another photo, Myleene is posing with a coconut as she sizzles on the white beach in a bright red bikini.
Making reference to the hit 2000 film Cast Away, which sees Tom Hanks' character makes friends with a coconut while stranded on an island, Myleene joked: "#wilson #wiiiiillllson #mexico."
