No, the first "Lord" is God The Father; the second one is Jesus. Jesus Himself makes that clear in Matt. 22. which Art cited.
I disagree, since Christ was referencing the second "Lord" which David mentioned, not the first "Lord". 


22:42 Saying, What think ye of Christ? whose son is he? They say unto him, The son of David.

22:43 He saith unto them, How then doth David in spirit call him Lord, saying,

22:44 The LORD said unto my Lord, Sit thou on my right hand, till I make thine enemies thy footstool?

Since the "son of David" is here being referred to, it is referring to the One being told to sit on David's throne--the second "Lord".  Yehovah is God, and God is the Father, the Word, and the Holy Ghost.  But I will not waste further time in discussing this with you since you have a tritheistic view of the Godhead.  If you don't understand that, it's not surprising you don't understand this either.
