Ava and Celine
A very complex relationship, they were first friends and worked competently together they still work well together albeit reluctantly due to Celine pursuing Red Velvet, Ava's boyfriend. Ava then swore that Celine was just using her to get to Red despite Celine wasn't. To make things worse Red Velvet was accepting Celines advances on him after swearing to Ava that she's the one he wants. Ava now hates Celine and Celine doesn't hate Ava but dislikes her for treating her so badly.
Ava unfortunately has Celine as an underling in her work team and knows changing would be stupid as Celine is a stand out star from her resume. 

Ava: "Darling that colour isnt correct go get a different swatch, i said Mauve that's Indigo
Celine: "Ava i need to speak with you about the preparation team"
Ava: "Now you there i need you go and give Miss Primrose these instructions for the models selection"
Celine: " Ava!! its urgent"
Ava: "What is it now Celine, what could be wrong?"
Celine: "Well i wanted to discuss your choices on my team? They seems rather inexperienced"
Ava: "Then train them its simple"
Celine: "I dont have the time Ava you know that, i can't go around training ponies when i still neeed to sort out the catering, make-up artists, theres still to much and not enough time" 
Ava: "Thats not my problem..mmm maybe your not as competent as i thought you were"
Celine: "Look you know im one of the best organisers here, your just jealous that Red is paying attention to me"
