June 5 (Reuters) - Lululemon Athletica ( LULU ) beat

Wall Street expectations for first-quarter revenue on Wednesday,

as strong international business helped buffer a slowdown in

consumer discretionary spending in its key North America market.

The athleisure apparel maker posts quarterly net revenue of

$2.21 billion, above analysts' average estimate of $2.19

billion, according to LSEG data.
