And despite his very public bed-hopping incident, 49-year-old Liz has nothing but good things to say about her ex.
Speaking on Watch What Happens on Tuesday evening, the Austin Powers actress played 'Plead the Fifth' and opted to answer all of Andy Cohen's questions.
Revealing why their 13-year romance really ended, the Gossip Girl star said:
'He remains my best friend to this day, but he used to really annoy me', she laughed. 'I love him, but he's very annoying.'
'My friends used to call him Grumpelstiltskin!', she giggled, revealing his moods were too much to handle '24/7'.
And despite Love Actually star Hugh putting his Pretty Woman style affair with Hollywood prostitute Divine Brown down to 'lack of sex' with Liz during his appearance on the same show last month, Liz had nothing but good things to say about her ex.
Rating his bedroom skills (yes really), the mother-of-one said:
'Oh really, a 10! I was with him for 13 years!'
The twosome have remained on good terms, and father-of-two Hugh is godfather to Liz's 12-year-old son Damian.
