Do you hear that? It's the sound of wedding bells ringing! Last year, we witnessed Prince Harry and Meghan Markle tying the knot in a lavish royal wedding, and this year, we have so many engagements to be excited about. Hilary Duff and Matthew Koma, Jennifer Lawrence and Cooke Maroney, and Katy Perry and Orlando Bloom are all getting ready to tie the knot, but we're not even through with the year. So, which celebrity couple will walk down the aisle next? We'll just have to wait and see.
