Fruit, round, as it happens (5)

I believe the answer is:

olive

'fruit' is the definition.
(I've seen this before)

'round as it happens' is the wordplay.
'round' becomes 'o' (round can mean a round object).
'as it happens' becomes 'live' (as in live television).
'o'+'live'='OLIVE'

(Other definitions for olive that I've seen before include "Small green tree-fruit, nice in martini" , "A Med. fruit" , "I love this fruit" , "Fruit; Popeye's girlfriend" , "One [TYPE OF TREE] is from the Mediterranean" .)

I've seen this clue in The Times.
