And when we say squeeze - we're talking about Harry's arm, which newly married Una is clinging on to in a bid to stay upright as the pair leave Rochelle Wiseman and Marvin Humes' wedding in the wee small hours of Saturday morning.
And One Direction fans can remain calm - also with the pair (and looking just as merry) was Una's new hubby, rugby star Ben Foden.
Fast forward a few hours and Una and Ben weren't looking quite so smiley as they left their hotel in Oxfordshire to head to yet more drinkies at the post wedding brunch.
Hair of the dog, Una?
Looking a little perkier were JB and Oritse of JLS who were all smiles as they made their way to the party.
The pair - along with fellow JLS star Aston - were groomsmen on the big day. They were joined by Rochelle's Saturdays bandmates who were all bridesmaids.
