It's a physical on-hit effect, so of Course it applys lifesteal. Similar abilities like Miss Fortunes Love Tap, Vaynes Tumble, Dravens Spinning Axe or Nasus Siphoning Strike behave the same way.

That the bonus damage was also increased by a critical strike however is doubtable. On-Hit effects don't crit, unless they have the additional effect that they do (like Vayne's Tumble did before the nerf). The attack from Queen's Wrath can crit as normal, the bonus damage however doesn't.
