Kate Beckinsale, 45, returns to Instagram after DELETING all posts... as she defended her romance with Pete Davidson, 25, on social media platform

Kate Beckinsale has returned to Instagram just six days after deleting all her posts.

The 45-year-old star returned to the picture-sharing social media platform on Thursday after a short hiatus.

She shared a photo of herself standing in front of a large plant while wearing an ovesized suit and vest combination.

Kate captioned the snap: 'Back to business. Also this is not a plant it is a painfully attached tail.'

Her highlighted tresses were worn down in a middle part as she flashed a sultry look at the camera.

She let her natural looks show with complementary make-up on her face topped off with shiny pink lip and blush.

This came just six days after Kate scrubbed her Instagram account of all posts on Friday morning with no explanation.

Recently, the brunette bombshell has found herself at the center of a media storm surrounding her May December romance with SNL star Pete Davidson, 25.

Beckinsale's Instagram is still active but with nothing to show her 2.8 million followers.

Kate was always quite active on the photo sharing platform, regularly posting Instagram Stories, photos and videos.

The Underworld star shared everything from stunning selfies to videos of her intense work out routines.

Her spontaneous move to rid the page of content could be part of a professional rebranding like Taylor Swift has done in the past.

It could also have something to do with Kate's new boyfriend, Ariana Grande's ex, Pete Davidson.

The newly minted couple has caught flack due to their 20 year age difference.

Perhaps not so ironically, last week actor David Spade left a barbed joke in a comment on one of Kate's Instagram posts.

The reason? Earlier this week Kate defended her new relationship with Pete Davidson on Instagram after actor David Spade left a joke about her penchant for young men on a video of the actress with a cub

Kate posted a sweet video of herself cuddling a baby cheetah, taken during filming for her new Amazon TV series, The Widow, in South Africa.

She captioned the clip: 'So many extraordinary experiences on #thewidow but this and seeing Charles Dance striding powerfully down a corridor in only a hotel robe and mirror aviators are among the standouts #thewidow #amazonprimevideo'.

The baby big cat lay on her lap as it licked her hands - and comedian David couldn't resist cracking a joke.

David commented: 'You like them young! (now dont fight back and roast me just quietly stew and take the hit) [sic]'.

Ignoring his request, Kate retorted: 'never going to happen grandpa'.

The couple made things official when they were spotted tongue kissing in the stands on March 3 at a New York Rangers game in New York City.

Pete was engaged last year to pop star Ariana Grande, 25, but they called it off and split last October.

The SNL star was spotted out on Thursday during a solo stroll without his new lady in Los Angeles.
