Fling or Ring? Calista and Harrison

AKA: The original lollypop lady, Ally McSqueal

Years racked up: 39

Known for?: Setting back the causes of feminism about 45 years with the intolerable drip-fest that was 'dramedy' Ally McBeal. Adopting a baby son. Being incredibly bony. Oh, and being a serious thesp sort, too.

Is involved in a love thing with...

Who? Harrison Ford

AKA: Harry, Indy, Hans...

Years racked up: A crinklesome 62

Known for?: Being one of Hollywood's original megastars, packing them in the aisles as the de-lovely Hans Solo in the Star Wars movies and as action archeologist Indiana Jones. Still part of the $25m-a-picture club (whew), this former carpenter is rumoured to be playing Indy once again. Indiana Jones and the Curse of the Nursing Home, perhaps?

Romance rocketed when: The May-to-December two began dating in early 2002, after Harrison separated from his wife, ET scribe Melissa Mathison. Since then, they've been trundling along quietly, more or less, barely whispering a word of their romance to the media. Spoilsports.

Make or break: Constant marriage rumours have swirled around the pair like a particularly determined mosquito since the beginning. Having finalised his divorce from Mathison earlier this year, latest reports have the pea-sized Calista issuing him an 'ultimatum' to settle down and walk her up the aisle. But despite Ford 'not allowing himself to be pushed into marrying her' (c.f. a tabloid 'source'), they're still together.

Soppy speak: Notoriously private, very few direct quotes can be attributed to either one of them over their relationship. Taciturn Harrison has eked out one measly comment about Flockhart, although it's barely juicy: "Surely, my most intimate relationship outside of my children is with her. And that meant a great deal to me." Right, but we need a few more details, y'know?

Biz Bitch says: Hardly the most exciting couple in Celebland, these barge-loving actors enjoy the quiet life (apart from when he's chucking her in rubbish bins, that is). Harrison's been burned by two very expensive divorces — he reportedly paid out a whacking $85m to Mathison — but Calista's approaching 40 without a ring on her finger. We'll see how long they last without that rock...
