Celebrities post sweet tributes and throwbacks for Mother's Day

These celebrities started from the bottom now they're here. But they would've never got to the top of their game without the unwavering support from their mothers.

The who's who of Hollywood took to Instagram on Mother's Day to honour their one and only in a series of sweet posts. From throwbacks to tributes, celebs happily gave their mums the spotlight.  

But all eyes were on Chris Pratt's dad when the actor posted a flashback pic -- because his late father looked more like Chris Pratt than Chris Pratt does!

Meanwhile, it wasn't all breakfast in bed and pamper sessions for some. Spare a thought for Orlando Bloom's mum, Sandi Copeland.

She proved that now matter the occasion, mums still put their children first. Get this: it was Sandi who stepped inside the kitchen to cook Orly his favourite stew!

Sigh, a mother's work is never done…
