"That's What Love Can Do" is a hit song by American female pop group Boy Krazy. The song was written and produced by British hitmaking team Stock Aitken Waterman, and first released in 1991 as Boy Krazy's debut single. Lead vocals were performed by group member Johnna Cummings. This was the only single in which group member Renée Veneziale would be involved in, leaving the band in 1991 soon after its release. The song peaked at #86 in the UK.

At the end of 1992, the song became successful in North American nightclubs, and radio airplay soon followed, prompting a re-release in early 1993. For this reissue, the song was remixed (the radio edit being an edit of the Hot Tracks remix, which was popular at nightclubs). The song was a success this time round, becoming the group's signature song, and peaking at #18 in the Billboard Hot 100. It also reached #1 in Pop airplay on the Radio & Records CHR/Pop chart, and #2 on the Top 40 Mainstream chart.

In the UK it was still not a big hit, peaking at #80.

The B-side on both releases was a cover of "One Thing Leads to Another", originally by the SAW-produced boyband Yell!. The lyrics were slightly rewritten on Boy Krazy's version to reflect the gender change. The original 1991 release featured Renée Veneziale singing the second verse, this was re-recorded by Josselyne Jones in the 1993 version, which can be found on the 1993 single and the Boy Krazy album.

Three videos were filmed:

The 1991 video has the girls in a revolving scenario, the five girls sitting in swivel chairs, radiators, and also holding an electric fan or on a phone booth, among other things.

The 1993 American video shows the girls in a bar, intercut with some scenes of the girls choreographing the song.

The 1993 British video mixed both previous video clips (with Renée Veneziale edited out of the parts containing the original video), with additional footage from the 1993 American video in it.
