How else to explain the outbreak of nest feathering by the long-running industry double act, who have just popped the question to their respective partners and look set to swap hedonism for domestic bliss?
Recently, Hurrell, 42, went on bended knee to Elvira, his partner and the mother of their eight-month-old son, Lucca.
Now MacLennan, 43, described in the Campaign A List as "an industry poster pin-up boy", has decided to do the decent thing by his lady, Wendy, who is expecting their second child in November.
The deed was done during a long weekend in Rome, during a complementary weekend at a plush city-centre hotel. "We were meant to go last October but the hotel cancelled us the day before because of problems with its water supply. It sure pays to complain. Not that I'm a cheapskate, mind," MacLennan says.
The thought never crossed our mind. Now what did you say your new package was as the chairman of the UK group?
Sadly, MacLennan's carefully laid plan to propose during a leisurely amble around St Peter's Square failed to materialise, so it had to be carried out in the hotel lobby, instead.
Did he have to get down on one knee? "Yes, she made me." And presumably there was a glittering rock with which to dazzle his conquest? "It was cut glass, actually, but she'll never know the difference." She will now, Moray. Better watch out for the flying plates when you get home tonight.
