Kimberly has spoken openly about her feud with Nicole in the past, which apparently started when the Pussycat Dolls began going their separate ways in 2010.
Last year, Kimberly told The Mirror: "I have not spoken to or seen Nicole in quite some time... and that's not through lack of trying.
"I've made enough first moves now, I feel the ball is in her court."
She also was quoted saying: "I have a lot of love for Nicole and if she offered [an olive branch] I would accept it with open arms."
Well, now it appears Nicole has done just that. On the weekend, Kimberly announced that she had married her boyfriend Max Rogers following a two-year engagement.
@KimberlyKWyatt Congratulations luv on getting married! Here's 2 new beginnings & new memories! Blessings, all my love & best wishes Nic xo— Nicole Scherzinger (@NicoleScherzy) February 27, 2014
Notably referencing "new beginnings", last night Nicole tweeted Kimberly directly, saying: "Congratulations luv on getting married! Here's 2 new beginnings & new memories! Blessings, all my love & best wishes Nic xo."
Kimberly has not posted on Twitter since 23 February, as she is no doubt enjoying a honeymoon with her new husband.
We'll be watching this space to see if she replies!
