The 45-year-old has taken up residency in Las Vegas and during one of her sold shows on Wednesday evening she re-affirmed her love for Aussie media mogul.
In a video obtained by TMZ, the loved-up star confessed to the crowd, “I have a new heart tonight. James is in my heart tonight.”
It was also reported that James, 47, was in the audience of Caesars Palace Colosseum where his new love was performing.
Following her sweet shout-out, Mariah sung an impassioned rendition of her hit song Hero and thus extinguished any speculation that the pair may already be heading for splitsville.
Earlier in the week, rumours swirled they may have gone their separate ways after not being spotted together in several weeks following their whirlwind romance in Capri which saw them practically joined at the hip for days on end.
Mimi also took to Instagram to share her joy writing, “Happy backstage right before last night’s show… #NTT ‘if you look inside your heart.'”
Since making their relationship public on a Mediterranean holiday, James and Mariah have traveled to Israel where they reportedly caught up with spiritual leaders for a “pre-engagement meeting.”
The Honey hitmaker will be returning to the holy land to perform in August, where she will pocket a cool $500,000 for the gig.
Wonder if she’ll give James another love song dedication?
