Winona Ryder has reportedly slammed her former lover Johnny Depp's engagement with Amber Heard by calling it 'inappropriate'.

Sources have revealed that the 42-year-old actress is really upset with the way Depp has conducted the affair and is put off by it, Metro.co.uk reported.

Insiders insisted that the 'Girl, Interrupted' actress can't stand how the 50-year-old actor's friends like Tim Burton are cheering this relationship.

Sources added that Ryder thinks it's a sad cliche that Depp has dumped his long-term baby mama Vanessa Paradis for a `woman in her twenties` and she is now soured on any plans of an acting reunion with him.
