You need 75% paragon/renegade to tell them both. If you have messed up, you need 100% paragon/renegade to get them to like you again. So it's best to have the 75% by that time, so neither of them die in the final mission.
To have a romance with Miranda (or Jack) you must always be nice to her. Always agree with her, and you must must must do her loyalty mission. Take lots of opportunities to talk to her, usually on the Normandy. At a certain point in the game, you'll find her and Jack fighting in Miranda's room. This will lead to you having to make a choice on who is right: Miranda or Jack. If you choose one of them, then your relationship with her will greatly raise. The other will get mad, and if you want them to forgive you, you must later talk to them and use either a renegade of paragon dialogue/influence line. Alternatively, during the fight you can use a renegade/paragon line to get them both to stop and prevent any hurt feelings.
You need to pass either a charm or intimidate check to get both of them loyal, the first time it's easier, if you fail you can come back later for a harder check. The check is based on how much paragon you have versus how much you could have earned so if you don't mix and match too much during the game and just go for paragon for example you should be able to pass the charm check without any problems, the same goes for the renegade and intimidate options obviously. if you go 50/50 on paragon and renegade options during your playthrough it will become harder and harder to pass and will at one point or another become impossible. The exact values for passing individual checks such as these are not known outside bioware but the above explanation is the general principle of it.
yes she does
they both sing.
they both hot
They are both ugly
Selena Gomez, because Miranda Cosgrove sucks at both at acting and singing.
Both singers are country singers. They are also both singer - songwriters. Luke Bryan uses vocals and an acoustic guitar, while Miranda Lambert uses vocals, guitar, and a saxaphone. They both have Nashville labels. Miranda's label's are Epic, Columbia Nashville, and RCA Records Nashville.
They are both the same height
Id have both

It's your opinion. I like them both. Miranda Cosgrove is very sweet & girly and Jennette McCurdy is funny & girly too.
