Trying to find old mills and boon 80's/90's

Hi I was wondering if someone could help me.

I'm looking for two mills and boon books maybe 80's/90's, they were the first mills&boon I ever read and I would really like to get new copies. 

1) I think it was set in Singapore, the cover was green and the man and woman on the front has black hair and was very very tanned. Anyway, the female lead (I think her name was Dion or something like that) ends up in a reluctant marriage to the hero (i can't remember his name). Then Dion's best friend Tony, gives them a picture of Dion as a wedding gift but the hero gets very angry about having a half naked picture of his wife and throws Tony out. The hero (if you can continue to call him that) proceeds to isolate Dion from Tony, but is happy to be around a woman (I think her name is Dana) that Dion is helplessly jealous of because she thinks she holds the hero's affections and the hero doesn't help absolve her fears. Dion still stays away from Tony but loses it when she sees the hero helping Dana? to his car with an arm around her shoulder. she rushes to find Tony and sits with him on a beach and the hero revs up in a white mercedes, drags her away from tony and I think he punches him. Then in the end, they fight and make up.

2) I don't remember much of at all compared to the first one lol. I remember the cover was blue and the man and woman both had black hair and she may have been wearing a blue sweater? Anyway the female lead is called Sam and I think she lands a job she practically wasn't going qualified for or ends up being dragged along by the hero who is her boss. I think it had something to do with photoshoots, either way they were on site for something. And the model? was really mean to Sam but he stood up for her. I remember the hero asking why people call her Sam and not Samantha, and she replied it was because Samantha was a feminine name and she wasn't feminine. That's all I remember lool

I would gladly appreciate the help xxxxxx
